8
9 =head1 DESCRIPTION
10
11 B<rxvt-unicode>, version B<@@RXVT_VERSION@@>, is a colour vt102 terminal
12 emulator intended as an I<xterm>(1) replacement for users who do not
13 require features such as Tektronix 4014 emulation and toolkit-style
14 configurability. As a result, B<rxvt-unicode> uses much less swap space --
15 a significant advantage on a machine serving many X sessions.
16
17 =head1 FREQUENTLY ASKED QUESTIONS
18
19 See @@RXVT_NAME@@(7) (try C<man 7 @@RXVT_NAME@@>) for a list of
20 frequently asked questions and answer to them and some common
21 problems. That document is also accessible on the World-Wide-Web at
22 L<http://cvs.schmorp.de/browse/rxvt-unicode/doc/rxvt.7.html>.
23
24 =head1 RXVT-UNICODE VS. RXVT
25
26 Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
27 internally. That means it can store and display most scripts in the
28 world. Being a terminal emulator, however, some things are very difficult,
29 especially cursive scripts such as arabic, vertically written scripts
30 like mongolian or scripts requiring extremely complex combining rules,
31 like tibetan or devenagari. Don't expect pretty output when using these
32 scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
33 fine, though. A somewhat difficult case are right-to-left scripts, such
34 as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
35 belong into the application, not the terminal emulator (too many things --
36 such as cursor-movement while editing -- break otherwise), but that might
37 change.
38
39 If you are looking for a terminal that supports more exotic scripts, let
40 me recommend C<mlterm>, which is a very user friendly, lean and clean
41 terminal emulator. In fact, the reason rxvt-unicode was born was solely
42 because the author couldn't get C<mlterm> to use one font for latin1 and
43 another for japanese.
44
45 Therefore another design rationale was the use of multiple fonts to
46 display characters: The idea of a single unicode font which many other
47 programs force onto its users never made sense to me: You should be able
48 to choose any font for any script freely.
49
50 Apart from that, rxvt-unicode is also much better internationalised than
51 its predecessor, supports things such as XFT and ISO 14755 that are handy
52 in i18n-environments, is faster, and has a lot bugs less than the original
53 rxvt. This all in addition to dozens of other small improvements.
54
55 It is still faithfully following the original rxvt idea of being lean
56 and nice on resources: for example, you can still configure rxvt-unicode
57 without most of its features to get a lean binary. It also comes with
58 a client/daemon pair that lets you open any number of terminal windows
59 from within a single process, which makes startup time very fast and
60 drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
61 @@RXVT_NAME@@c(1) (client).
62
63 It also makes technical information about escape sequences (which have
64 been extended) more accessible: see @@RXVT_NAME@@(7) for technical
65 reference documentation (escape sequences etc.).
66
67 =head1 OPTIONS
68
69 The B<@@RXVT_NAME@@> options (mostly a subset of I<xterm>'s) are listed
70 below. In keeping with the smaller-is-better philosophy, options may be
71 eliminated or default values chosen at compile-time, so options and
72 defaults listed may not accurately reflect the version installed on
73 your system. `@@RXVT_NAME@@ -h' gives a list of major compile-time options on
74 the I<Options> line. Option descriptions may be prefixed with which
75 compile option each is dependent upon. e.g. `Compile I<XIM>:' requires
76 I<XIM> on the I<Options> line. Note: `@@RXVT_NAME@@ -help' gives a list of all
77 command-line options compiled into your version.
78
79 Note that B<@@RXVT_NAME@@> permits the resource name to be used as a
80 long-option (--/++ option) so the potential command-line options are
81 far greater than those listed. For example: `@@RXVT_NAME@@ --loginShell --color1
82 Orange'.
83
84 The following options are available:

185 Select the fonts to be used. This is a comma separated list of font names
186 that are checked in order when trying to find glyphs for characters. The
187 first font defines the cell size for characters; other fonts might be
188 smaller, but not (in general) larger. A (hopefully) reasonable default
189 font list is always appended to it. See resource B<font> for more details.
190
191 In short, to specify an X11 core font, just specify its name or prefix it
192 with C<x:>. To specify an XFT-font, you need to prefix it with C<xft:>,

415
416 =item B<-hold>|B<+hold>
417
418 Turn on/off hold window after exit support. If enabled, @@RXVT_NAME@@
419 will not immediately destroy its window when the program executed within
420 it exits. Instead, it will wait till it is being killed or closed by the
421 user; resource B<hold>.

424
425 Remap a key symbol. See resource B<keysym>.
426
427 =item B<-embed> I<windowid>
428
429 Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
430 which enables applications to easily embed a terminal.
431
432 Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
433 shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
434 quite a bit, so don't expect it to keep some specific state. It's best to
435 create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
436
437 The window will not be destroyed when @@RXVT_NAME@@ exits.
438
439 It might be useful to know that @@RXVT_NAME@@ will not close file
440 descriptors passed to it (except for stdin/out/err, of course), so you
441 can use file descriptors to communicate with the programs within the
442 terminal. This works regardless of whether the C<-embed> option was used or
443 not.
444
445 Here is a short Gtk2-perl snippet that illustrates how this option can be
446 used (a longer example is in F<doc/embed>):
447
448 my $rxvt = new Gtk2::Socket;
449 $rxvt->signal_connect_after (realize => sub {
450 my $xid = $_[0]->window->get_xid;
451 system "@@RXVT_NAME@@ -embed $xid &";
452 });
453
454 =item B<-pty-fd> I<file descriptor>
455
456 Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
457 pair but instead use the given file descriptor as the tty master. This is
458 useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
459 without having to run a program within it.
460
461 If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
462 entries and will not tinker with pty/tty permissions - you have to do that
463 yourself if you want that.
464
465 As an extremely special case, specifying C<-1> will completely suppress
466 pty/tty operations.
467
468 Here is a example in perl that illustrates how this option can be used (a
469 longer example is in F<doc/pty-fd>):
470
471 use IO::Pty;
472 use Fcntl;
473
474 my $pty = new IO::Pty;
475 fcntl $pty, F_SETFD, 0; # clear close-on-exec
476 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
477 close $pty;
478
479 # now communicate with rxvt
480 my $slave = $pty->slave;
481 while (<$slave>) { print $slave "got <$_>\n" }

490 =head1 RESOURCES (available also as long-options)
491
492 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
493 options) compiled into your version.
494
495 You can set and change the resources using X11 tools like B<xrdb>. Many
496 distribution do also load settings from the B<~/.Xresources> file when X
497 starts. @@RXVT_NAME@@ will consult the following files/resources in order,
498 with later settings overwriting earlier ones:
499
500 1. system-wide app-defaults file, either locale-dependent OR global
501 2. app-defaults file in $XAPPLRESDIR
502 3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
503 4. SCREEN_RESOURCES for the current screen
504 5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
505
506 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two class
507 names: B<Rxvt> and B<URxvt>. The class name B<Rxvt> allows resources
508 common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be easily
509 configured, while the class name B<URxvt> allows resources unique to
510 B<@@RXVT_NAME@@>, to be shared between different B<@@RXVT_NAME@@>
511 configurations. If no resources are specified, suitable defaults will
512 be used. Command-line arguments can be used to override resource
513 settings. The following resources are supported (you might want to
514 check the @@RXVT_NAME@@perl(3) manpage for additional settings by perl
515 extensions not documented here):

546 names used are listed in the B<COLORS AND GRAPHICS> section.
547
548 Colours higher than 15 cannot be set using resources (yet), but can be
549 changed using an escape command (see @@RXVT_NAME@@(7)).
550
551 Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
552 88 colour support). Colours 80-87 are evenly spaces grey steps.
553
554 =item B<colorBD:> I<colour>
555
556 =item B<colorIT:> I<colour>
557
558 Use the specified colour to display bold or italic characters when the
559 foreground colour is the default. If font styles are not available
560 (Compile I<styles>) and this option is unset, reverse video is used instead.
561
562 =item B<colorUL:> I<colour>
563
564 Use the specified colour to display underlined characters when the
565 foreground colour is the default.
566
567 =item B<colorRV:> I<colour>
568
569 Use the specified colour as the background for reverse video characters
570 when OPTION_HC is disabled (--disable-frills).
571
572 =item B<underlineColor:> I<colour>
573
574 If set, use the specified colour as the colour for the underline
575 itself. If unset, use the foreground colour.
576
577 =item B<cursorColor:> I<colour>
578
579 Use the specified colour for the cursor. The default is to use the
580 foreground colour; option B<-cr>.
581
582 =item B<cursorColor2:> I<colour>
583
584 Use the specified colour for the colour of the cursor text. For this to
585 take effect, B<cursorColor> must also be specified. The default is to
586 use the background colour.
587
588 =item B<reverseVideo:> I<boolean>
589
590 B<True>: simulate reverse video by foreground and background colours;
591 option B<-rv>. B<False>: regular screen colours [default]; option
592 B<+rv>. See note in B<COLORS AND GRAPHICS> section.
593
594 =item B<jumpScroll:> I<boolean>
595
596 B<True>: specify that jump scrolling should be used. When scrolling
597 quickly, fewer screen updates are performed [default]; option B<-j>.
598 B<False>: specify that smooth scrolling should be used; option B<+j>.
599
600 =item B<inheritPixmap:> I<boolean>
601
602 B<True>: make the background inherit the parent windows' pixmap, giving
603 artificial transparency. B<False>: do not inherit the parent windows'
604 pixmap.
605
606 I<Please note that transparency of any kind if completely unsupported by
607 the author. Don't bug him with installation questions!>
608
609 =item B<fading:> I<number>
610
611 Fade the text by the given percentage when focus is lost; option B<-fade>.
612
613 =item B<fadeColor:> I<colour>
614
615 Fade to this colour, when fading is used (see B<fading:>). The default
616 colour is black; option B<-fadecolor>.
617
618 =item B<tintColor:> I<colour>
619
620 Tint the transparent background pixmap with the given colour; option
621 B<-tint>.
622
623 =item B<shading:> I<number>
624
625 Darken (0 .. 100) or lighten (-1 .. -100) the transparent background image
626 in addition to tinting it; option B<-sh>.
627
628 =item B<scrollColor:> I<colour>
629
630 Use the specified colour for the scrollbar [default #B2B2B2].
631
632 =item B<troughColor:> I<colour>
633
634 Use the specified colour for the scrollbar's trough area [default
635 #969696]. Only relevant for rxvt (non XTerm/NeXT) scrollbar.
636
637 =item B<borderColor:> I<colour>
638
639 The colour of the border around the text area and between the scrollbar
640 and the text.
641
642 =item B<backgroundPixmap:> I<file[;geom]>
643
644 Use the specified XPM file (note the `.xpm' extension is optional) for
645 the background and also optionally specify its scaling with a geometry
646 string B<WxH+X+Y>, in which B<"W" / "H"> specify the
647 horizontal/vertical scale (percent) and B<"X" / "Y"> locate the image
648 centre (percent). A scale of 0 displays the image with tiling. A scale
649 of 1 displays the image without any scaling. A scale of 2 to 9
650 specifies an integer number of images in that direction. No image will
651 be magnified beyond 10 times its original size. The maximum permitted
652 scale is 1000. [default 0x0+50+50]
653
654 =item B<path:> I<path>
655
656 Specify the colon-delimited search path for finding XPM files.
657
658 =item B<font:> I<fontlist>
659
660 Select the fonts to be used. This is a comma separated list of font names
661 that are checked in order when trying to find glyphs for characters. The
662 first font defines the cell size for characters; other fonts might be
663 smaller, but not (in general) larger. A (hopefully) reasonable default
664 font list is always appended to it; option B<-fn>.
665
666 Each font can either be a standard X11 core font (XLFD) name, with
667 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
668
669 In addition, each font can be prefixed with additional hints and
670 specifications enclosed in square brackets (C<[]>). The only available
671 hint currently is C<codeset=codeset-name>, and this is only used for Xft
672 fonts.
673
674 For example, this font resource
675
676 URxvt.font: 9x15bold,\
677 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
678 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
679 [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
680 xft:Code2000:antialias=false
681
682 specifies five fonts to be used. The first one is C<9x15bold> (actually
683 the iso8859-1 version of the second font), which is the base font (because
684 it is named first) and thus defines the character cell grid to be 9 pixels
685 wide and 15 pixels high.
686
687 The second font is just used to add additional unicode characters not in
688 the base font, likewise the third, which is unfortunately non-bold, but
689 the bold version of the font does contain less characters, so this is a
690 useful supplement.
691
692 The third font is an Xft font with aliasing turned off, and the characters
693 are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
694 contains other characters, but we are not interested in them.
695
696 The last font is a useful catch-all font that supplies most of the
697 remaining unicode characters.
698
699 =item B<boldFont:> I<fontlist>
700
701 =item B<italicFont:> I<fontlist>
702
703 =item B<boldItalicFont:> I<fontlist>
704
705 The font list to use for displaying B<bold>, I<italic> or B<< I<bold
706 italic> >> characters, respectively.
707
708 If specified and non-empty, then the syntax is the same as for the
709 B<font>-resource, and the given font list will be used as is, which makes
710 it possible to substitute completely different font styles for bold and
711 italic.
712
713 If unset (the default), a suitable font list will be synthesized by
714 "morphing" the normal text font list into the desired shape. If that is
715 not possible, replacement fonts of the desired shape will be tried.
716
717 If set, but empty, then this specific style is disabled and the normal
718 text font will being used for the given style.
719
720 =item B<intensityStyles:> I<boolean>
721
722 When font styles are not enabled, or this option is enabled (B<True>,
723 option B<-is>, the default), bold and italic font styles imply high
724 intensity foreground/background colours. Disabling this option (B<False>,
725 option B<+is>) disables this behaviour, the high intensity colours are not
726 reachable.
727
728 =item B<selectstyle:> I<mode>
729
730 Set mouse selection style to B<old> which is 2.20, B<oldword> which is
731 xterm style with 2.20 old word selection, or anything else which gives
732 xterm style selection.
733
734 =item B<scrollstyle:> I<mode>
735
736 Set scrollbar style to B<rxvt>, B<plain>, B<next> or B<xterm>. B<plain> is
737 the author's favourite.
738
739 =item B<title:> I<string>
740
741 Set window title string, the default title is the command-line
742 specified after the B<-e> option, if any, otherwise the application
743 name; option B<-title>.
744
745 =item B<iconName:> I<string>
746
747 Set the name used to label the window's icon or displayed in an icon
748 manager window, it also sets the window's title unless it is explicitly
749 set; option B<-n>.
750
751 =item B<mapAlert:> I<boolean>
752
753 B<True>: de-iconify (map) on receipt of a bell character. B<False>: no
754 de-iconify (map) on receipt of a bell character [default].
755
756 =item B<urgentOnBell:> I<boolean>
757
758 B<True>: set the urgency hint for the wm on receipt of a bell character.
759 B<False>: do not set the urgency hint [default].
760
761 =item B<visualBell:> I<boolean>
762
763 B<True>: use visual bell on receipt of a bell character; option B<-vb>.
764 B<False>: no visual bell [default]; option B<+vb>.
765
766 =item B<loginShell:> I<boolean>
767
768 B<True>: start as a login shell by prepending a `-' to B<argv[0]> of
769 the shell; option B<-ls>. B<False>: start as a normal sub-shell
770 [default]; option B<+ls>.
771
772 =item B<utmpInhibit:> I<boolean>
773
774 B<True>: inhibit writing record into the system log file B<utmp>;
775 option B<-ut>. B<False>: write record into the system log file B<utmp>
776 [default]; option B<+ut>.
777
778 =item B<print-pipe:> I<string>
779
780 Specify a command pipe for vt100 printer [default I<lpr(1)>]. Use
781 B<Print> to initiate a screen dump to the printer and B<Ctrl-Print> or
782 B<Shift-Print> to include the scrollback as well.
783
784 The string will be interpreted as if typed into the shell as-is.
785
786 Example:
787
788 URxvt.print-pipe: cat > $(TMPDIR=$HOME mktemp urxvt.XXXXXX)
789
790 This creates a new file in your home directory with the screen contents
791 every time you hit C<Print>.
792
793 =item B<scrollBar:> I<boolean>
794
795 B<True>: enable the scrollbar [default]; option B<-sb>. B<False>:
796 disable the scrollbar; option B<+sb>.
797
798 =item B<scrollBar_right:> I<boolean>
799
800 B<True>: place the scrollbar on the right of the window; option B<-sr>.
801 B<False>: place the scrollbar on the left of the window; option B<+sr>.
802
803 =item B<scrollBar_floating:> I<boolean>
804
805 B<True>: display an rxvt scrollbar without a trough; option B<-st>.
806 B<False>: display an rxvt scrollbar with a trough; option B<+st>.
807
808 =item B<scrollBar_align:> I<mode>
809
810 Align the B<top>, B<bottom> or B<centre> [default] of the scrollbar
811 thumb with the pointer on middle button press/drag.
812
813 =item B<scrollTtyOutput:> I<boolean>
814
815 B<True>: scroll to bottom when tty receives output; option B<-si>.
816 B<False>: do not scroll to bottom when tty receives output; option
817 B<+si>.
818
819 =item B<scrollWithBuffer:> I<boolean>
820
821 B<True>: scroll with scrollback buffer when tty receives new lines (and
822 B<scrollTtyOutput> is False); option B<-sw>. B<False>: do not scroll
823 with scrollback buffer when tty receives new lines; option B<+sw>.
824
825 =item B<scrollTtyKeypress:> I<boolean>
826
827 B<True>: scroll to bottom when a non-special key is pressed. Special keys
828 are those which are intercepted by rxvt-unicode for special handling and
829 are not passed onto the shell; option B<-sk>. B<False>: do not scroll to
830 bottom when a non-special key is pressed; option B<+sk>.
831
832 =item B<saveLines:> I<number>
833
834 Save I<number> lines in the scrollback buffer [default 64]. This
835 resource is limited on most machines to 65535; option B<-sl>.
836
837 =item B<internalBorder:> I<number>
838
839 Internal border of I<number> pixels. This resource is limited to 100;
840 option B<-b>.
841
842 =item B<externalBorder:> I<number>
843
844 External border of I<number> pixels. This resource is limited to 100;
845 option B<-w>, B<-bw>, B<-borderwidth>.
846
847 =item B<borderLess:> I<boolean>
848
849 Set MWM hints to request a borderless window, i.e. if honoured by the
850 WM, the rxvt-unicode window will not have window decorations; option B<-bl>.
851
852 =item B<skipBuiltinGlyphs:> I<boolean>
853
854 Compile I<frills>: Disable the usage of the built-in block graphics/line
855 drawing characters and just rely on what the specified fonts provide. Use
856 this if you have a good font and want to use its block graphic glyphs;
857 option B<-sbg>.
858
859 =item B<termName:> I<termname>
860
861 Specifies the terminal type name to be set in the B<TERM> environment
862 variable; option B<-tn>.
863
864 =item B<linespace:> I<number>
865
866 Specifies number of lines (pixel height) to insert between each row of
867 the display [default 0]; option B<-lsp>.
868
869 =item B<meta8:> I<boolean>
870
871 B<True>: handle Meta (Alt) + keypress to set the 8th bit. B<False>:
872 handle Meta (Alt) + keypress as an escape prefix [default].
873
874 =item B<mouseWheelScrollPage:> I<boolean>
875
876 B<True>: the mouse wheel scrolls a page full. B<False>: the mouse wheel
877 scrolls five lines [default].
878
879 =item B<pastableTabs:> I<boolean>
880
881 B<True>: store tabs as wide characters. B<False>: interpret tabs as cursor
882 movement only; option C<-ptab>.
883
884 =item B<cursorBlink:> I<boolean>
885
886 B<True>: blink the cursor. B<False>: do not blink the cursor [default];
887 option B<-bc>.
888
889 =item B<pointerBlank:> I<boolean>
890
891 B<True>: blank the pointer when a key is pressed or after a set number
892 of seconds of inactivity. B<False>: the pointer is always visible
893 [default].
894
895 =item B<pointerColor:> I<colour>
896
897 Mouse pointer foreground colour.
898
899 =item B<pointerColor2:> I<colour>
900
901 Mouse pointer background colour.
902
903 =item B<pointerBlankDelay:> I<number>
904
905 Specifies number of seconds before blanking the pointer [default 2]. Use a
906 large number (e.g. C<987654321>) to effectively disable the timeout.
907
908 =item B<backspacekey:> I<string>
909
910 The string to send when the backspace key is pressed. If set to B<DEC>
911 or unset it will send B<Delete> (code 127) or, if shifted, B<Backspace>
912 (code 8) - which can be reversed with the appropriate DEC private mode
913 escape sequence.
914
915 =item B<deletekey:> I<string>
916
917 The string to send when the delete key (not the keypad delete key) is
918 pressed. If unset it will send the sequence traditionally associated
919 with the B<Execute> key.
920
921 =item B<cutchars:> I<string>
922
923 The characters used as delimiters for double-click word selection
924 (whitespace delimiting is added automatically if resource is given).
925
926 When the selection extension is in use (the default if compiled in, see
927 the @@RXVT_NAME@@perl(3) manpage), a suitable regex using these characters
928 will be created (if the resource exists, otherwise, no regex will be
929 created). In this mode, characters outside ISO-8859-1 can be used.
930
931 When the selection extension is not used, only ISO-8859-1 characters can
932 be used. If not specified, the built-in default is used:
933
934 B<< BACKSLASH `"'&()*,;<=>?@[]{|} >>
935
936 =item B<preeditType:> I<style>
937
938 B<OverTheSpot>, B<OffTheSpot>, B<Root>; option B<-pt>.
939
940 =item B<inputMethod:> I<name>
941
942 I<name> of inputMethod to use; option B<-im>.
943
944 =item B<imLocale:> I<name>
945
946 The locale to use for opening the IM. You can use an C<LC_CTYPE> of e.g.
947 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
948 input extension to be able to input japanese characters while staying in
949 another locale; option B<-imlocale>.
950
951 =item B<imFont:> I<fontset>
952
953 Specify the font-set used for XIM styles C<OverTheSpot> or
954 C<OffTheSpot>. It must be a standard X font set (XLFD patterns separated
955 by commas), i.e. it's not in the same format as the other font lists used
956 in @@RXVT_NAME@@. The default will be set-up to chose *any* suitable found
957 found, preferably one or two pixels differing in size to the base font.
958 option B<-imfont>.
959
960 =item B<tripleclickwords:> I<boolean>
961
962 Change the meaning of triple-click selection with the left mouse
963 button. Instead of selecting a full line it will extend the selection to
964 the end of the logical line only; option B<-tcw>.
965
966 =item B<insecure:> I<boolean>
967
968 Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
969 echo arbitrary strings like the icon name or the locale. This could be
970 abused if somebody gets 8-bit-clean access to your display, whether
971 through a mail client displaying mail bodies unfiltered or through
972 write(1) or any other means. Therefore, these sequences are disabled by
973 default. (Note that many other terminals, including xterm, have these
974 sequences enabled by default, which doesn't make it safer, though).
975
976 You can enable them by setting this boolean resource or specifying
977 B<-insecure> as an option. At the moment, this enables display-answer,
978 locale, findfont, icon label and window title requests.
979
980 =item B<modifier:> I<modifier>
981
982 Set the key to be interpreted as the Meta key to: B<alt>, B<meta>,
983 B<hyper>, B<super>, B<mod1>, B<mod2>, B<mod3>, B<mod4>, B<mod5>; option
984 B<-mod>.
985
986 =item B<answerbackString:> I<string>
987
988 Specify the reply rxvt-unicode sends to the shell when an ENQ (control-E)
989 character is passed through. It may contain escape values as described
990 in the entry on B<keysym> following.
991
992 =item B<secondaryScreen:> I<boolean>
993
994 Turn on/off secondary screen (default enabled).
995
996 =item B<secondaryScroll:> I<boolean>
997
998 Turn on/off secondary screen scroll (default enabled). If this
999 option is enabled, scrolls on the secondary screen will change the
1000 scrollback buffer and switching to/from the secondary screen will
1001 instead scroll the screen up.
1002
1003 =item B<hold>: I<boolean>
1004
1005 Turn on/off hold window after exit support. If enabled, @@RXVT_NAME@@
1006 will not immediately destroy its window when the program executed within
1007 it exits. Instead, it will wait till it is being killed or closed by the
1008 user.
1009
1010 =item B<keysym.>I<sym>: I<string>
1011
1012 Compile I<frills>: Associate I<string> with keysym I<sym>. The
1013 intervening resource name B<keysym.> cannot be omitted.
1014
1015 The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1016 any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1017 B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1018 and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1019 B<2>, B<3>, B<4>, B<5>.
1020
1021 The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1022 whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1023 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1024 current application keymap mode state.
1025
1026 The spellings of I<key> can be obtained by using B<xev>(1) command or
1027 searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1028 omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1029 keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1030 performed in an exact manner; however, the closest match is assured.
1031
1032 I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
1033 C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
1034 C<\000>: octal number) or verbatim control characters (C<^?>: delete,
1035 C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1036 can start or end with whitespace. B<This feature is deprecated and will
1037 be removed>.
1038
1039 Please note that you need to double the C<\> in resource files, as
1040 Xlib itself does its own de-escaping (you can use C<\033> instead of
1041 C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own
1042 processing).
1043
1044 You can define a range of keysyms in one shot by providing a I<string>
1045 with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1046 should be a character not used by the strings.
1047
1048 Its usage can be demonstrated by an example:
1049
1050 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1051
1052 The above line is equivalent to the following three lines:
1053

1057
1058 If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1059 is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1060 example the following means "change the current locale to C<zh_CN.GBK>
1061 when Control-Meta-c is being pressed":
1062
1063 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1064
1065 If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1066 is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1067 manpage. For example, the F<selection> extension (activated via
1068 C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1069
1070 URxvt.keysym.M-C-c: perl:selection:rot13
1071
1072 Due the the large number of modifier combinations, a defined key mapping
1073 will match if at I<at least> the specified identifiers are being set, and
1074 no other key mappings with those and more bits are being defined. That
1075 means that defining a key map for C<a> will automatically provide
1076 definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1077 mappings themselves.
1078
1079 Unfortunately, this will override built-in key mappings. For example
1080 if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1081 C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1082 user-defined keymap using the C<builtin:> replacement:
1083
1084 URxvt.keysym.Insert: <my insert key sequence>
1085 URxvt.keysym.S-Insert: builtin:
1086
1087 The first line defines a mapping for C<Insert> and I<any> combination
1088 of modifiers. The second line re-establishes the default mapping for
1089 C<Shift-Insert>.
1090
1091 The following example will map Control-Meta-1 and Control-Meta-2 to
1092 the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1093 font-switching at runtime:
1094
1095 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1096 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1097
1098 Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1099 info):
1100
1101 URxvt.keysym.M-C-3: command:\033[8;25;80t

1108 Comma-separated list(s) of perl extension scripts (default: C<default>) to
1109 use in this terminal instance; option B<-pe>.
1110
1111 Extension names can be prefixed with a C<-> sign to prohibit using
1112 them. This can be useful to selectively disable some extensions loaded
1113 by default, or specified via the C<perl-ext-common> resource. For
1114 example, C<default,-selection> will use all the default extension except
1115 C<selection>.
1116
1117 Extension names can also be followed by an argument in angle brackets
1118 (e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1119 searchable scrollback to Alt/Meta-s). Mentioning the same extension
1120 multiple times with different arguments will pass multiple arguments to
1121 the extension.
1122
1123 Each extension is looked up in the library directories, loaded if
1124 necessary, and bound to the current terminal instance.
1125
1126 If both of these resources are the empty string, then the perl
1127 interpreter will not be initialized. The idea behind two options is that
1128 B<perl-ext-common> will be used for extensions that should be available to
1129 all instances, while B<perl-ext> is used for specific instances.

1178 =head1 THE SCROLLBAR
1179
1180 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
1181 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1182 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1183 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1184 arrows and its behaviour mimics that of I<xterm>
1185
1186 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
1187 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.

1191
1192 To temporarily override mouse reporting, for either the scrollbar or
1193 the normal text selection/insertion, hold either the Shift or the Meta
1194 (Alt) key while performing the desired mouse action.
1195
1196 If mouse reporting mode is active, the normal scrollbar actions are
1197 disabled -- on the assumption that we are using a fullscreen
1198 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1199 (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the
1200 up and down arrows sends B<ESC [ A> (Up) and B<ESC [ B> (Down),
1201 respectively.
1202
1203 =head1 TEXT SELECTION AND INSERTION

1236
1237 Changing fonts (or font sizes, respectively) via the keypad is not yet
1238 supported in rxvt-unicode. Bug me if you need this.
1239
1240 You can, however, switch fonts at runtime using escape sequences, e.g.:
1241
1242 printf '\e]710;%s\007' "9x15bold,xft:Kochi Gothic"
1243
1244 You can use keyboard shortcuts, too:
1245
1246 URxvt.keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
1247 URxvt.keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
1248
1249 rxvt-unicode will automatically re-apply these fonts to the output so far.
1250
1251 =head1 ISO 14755 SUPPORT
1252
1253 ISO 14755 is a standard for entering and viewing unicode characters
1254 and character codes using the keyboard. It consists of 4 parts. The
1255 first part is available rxvt-unicode has been compiled with
1256 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1257 with C<--enable-iso14755>.
1258
1259 =over 4
1260
1261 =item * 5.1: Basic method
1262
1263 This allows you to enter unicode characters using their hexcode.
1264
1265 Start by pressing and holding both C<Control> and C<Shift>, then enter
1266 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1267 commit the character as if it were typed directly. While holding down
1268 C<Control> and C<Shift> you can also enter multiple characters by pressing
1269 C<Space>, which will commit the current character and lets you start a new
1270 one.
1271
1272 As an example of use, imagine a business card with a japanese e-mail
1273 address, which you cannot type. Fortunately, the card has the e-mail
1274 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1275 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1276 followed by releasing the modifier keys.
1277
1278 =item * 5.2: Keyboard symbols entry method
1279
1280 This mode lets you input characters representing the keycap symbols of
1281 your keyboard, if representable in the current locale encoding.
1282
1283 Start by pressing C<Control> and C<Shift> together, then releasing
1284 them. The next special key (cursor keys, home etc.) you enter will not
1285 invoke its usual function but instead will insert the corresponding
1286 keycap symbol. The symbol will only be entered when the key has been
1287 released, otherwise pressing e.g. C<Shift> would enter the symbol for
1288 C<ISO Level 2 Switch>, although your intention might have been to enter a
1289 reverse tab (Shift-Tab).
1290
1291 =item * 5.3: Screen-selection entry method
1292
1293 While this is implemented already (it's basically the selection
1294 mechanism), it could be extended by displaying a unicode character map.
1295
1296 =item * 5.4: Feedback method for identifying displayed characters for later input
1297
1298 This method lets you display the unicode character code associated with
1299 characters already displayed.
1300
1301 You enter this mode by holding down C<Control> and C<Shift> together, then
1302 pressing and holding the left mouse button and moving around. The unicode
1303 hex code(s) (it might be a combining character) of the character under the
1304 pointer is displayed until you release C<Control> and C<Shift>.
1305
1306 In addition to the hex codes it will display the font used to draw this
1307 character - due to implementation reasons, characters combined with
1308 combining characters, line drawing characters and unknown characters will
1309 always be drawn using the built-in support font.

1313 With respect to conformance, rxvt-unicode is supposed to be compliant to
1314 both scenario A and B of ISO 14755, including part 5.2.

1316 =head1 LOGIN STAMP
1317
1318 B<@@RXVT_NAME@@> tries to write an entry into the I<utmp>(5) file so that
1319 it can be seen via the I<who(1)> command, and can accept messages. To

1322
1323 =head1 COLORS AND GRAPHICS
1324
1325 In addition to the default foreground and background colours,
1326 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1327 high-intensity bold/blink versions of the same). Here is a list of the
1328 colours with their names.
1329
1330 =begin table
1331
1332 B<color0> (black) = Black
1333 B<color1> (red) = Red3
1334 B<color2> (green) = Green3
1335 B<color3> (yellow) = Yellow3
1336 B<color4> (blue) = Blue3
1337 B<color5> (magenta) = Magenta3
1338 B<color6> (cyan) = Cyan3
1339 B<color7> (white) = AntiqueWhite
1340 B<color8> (bright black) = Grey25
1341 B<color9> (bright red) = Red
1342 B<color10> (bright green) = Green
1343 B<color11> (bright yellow) = Yellow
1344 B<color12> (bright blue) = Blue
1345 B<color13> (bright magenta) = Magenta
1346 B<color14> (bright cyan) = Cyan
1347 B<color15> (bright white) = White
1348 B<foreground> = Black
1349 B<background> = White
1350
1351 =end table
1352
1353 It is also possible to specify the colour values of B<foreground>,
1354 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1355 a number 0-15, as a convenient shorthand to reference the colour name of
1356 color0-color15.
1357
1358 In addition to the colours defined above, @@RXVT_NAME@@ offers an
1359 additional 72 colours. The first 64 of those (with indices 16 to 79)
1360 consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
1361 16>), followed by 8 additional shades of gray (with indices 80 to 87).
1362
1363 Together, all those colours implement the 88 colour xterm colours. Only
1364 the first 16 can be changed using resources currently, the rest can only
1365 be changed via command sequences ("escape codes").
1366
1367 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1368 always swapping the foreground/background colours. This is in contrast to
1369 I<xterm>(1) where the colours are only swapped if they have not otherwise
1370 been specified. For example,
1371
1372 =over 4
1373
1374 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1375
1376 would yield White on Black, while on I<xterm>(1) it would yield Black
1377 on White.

1379 =back
1380
1381 =head2 ALPHA CHANNEL SUPPORT
1382
1383 If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1384 their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1385 (recommended, but B<MUST> have 4 digits/component) colour specifications,
1386 in addition to the ones provided by X, where the additional A component
1387 specifies opacity (alpha) values. The minimum value of C<0> is completely
1388 transparent). You can also prefix any color with C<[percent]>, where
1389 C<percent> is a decimal percentage (0-100) that specifies the opacity of
1390 the color, where C<0> is completely transparent and C<100> is completelxy
1391 opaque.
1392
1393 You probably need to specify B<"-depth 32">, too, and have the luck that
1394 your X-server uses ARGB pixel layout, as X is far from just supporting
1395 ARGB visuals out of the box, and rxvt-unicode just fudges around.
1396
1397 For example, the following selects an almost completely transparent red
1398 background, and an almost opaque pink foreground:
