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:>,

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

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

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

546 3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
547 names used are listed in the B<COLORS AND GRAPHICS> section.
548
549 Colours higher than 15 cannot be set using resources (yet), but can be
550 changed using an escape command (see @@RXVT_NAME@@(7)).
551
552 Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
553 88 colour support). Colours 80-87 are evenly spaces grey steps.
554
555 =item B<colorBD:> I<colour>
556
557 =item B<colorIT:> I<colour>
558
559 Use the specified colour to display bold or italic characters when the
560 foreground colour is the default. If font styles are not available
561 (Compile I<styles>) and this option is unset, reverse video is used instead.
562
563 =item B<colorUL:> I<colour>
564
565 Use the specified colour to display underlined characters when the
566 foreground colour is the default.
567
568 =item B<colorRV:> I<colour>
569
570 Use the specified colour as the background for reverse video characters
571 when OPTION_HC is disabled (--disable-frills).
572
573 =item B<underlineColor:> I<colour>
574
575 If set, use the specified colour as the colour for the underline
576 itself. If unset, use the foreground colour.
577
578 =item B<cursorColor:> I<colour>
579
580 Use the specified colour for the cursor. The default is to use the
581 foreground colour; option B<-cr>.
582
583 =item B<cursorColor2:> I<colour>
584
585 Use the specified colour for the colour of the cursor text. For this to
586 take effect, B<cursorColor> must also be specified. The default is to
587 use the background colour.
588
589 =item B<reverseVideo:> I<boolean>
590
591 B<True>: simulate reverse video by foreground and background colours;
592 option B<-rv>. B<False>: regular screen colours [default]; option
593 B<+rv>. See note in B<COLORS AND GRAPHICS> section.
594
595 =item B<jumpScroll:> I<boolean>
596
597 B<True>: specify that jump scrolling should be used. When scrolling
598 quickly, fewer screen updates are performed [default]; option B<-j>.
599 B<False>: specify that smooth scrolling should be used; option B<+j>.
600
601 =item B<inheritPixmap:> I<boolean>
602
603 B<True>: make the background inherit the parent windows' pixmap, giving
604 artificial transparency. B<False>: do not inherit the parent windows'
605 pixmap.
606
607 I<Please note that transparency of any kind if completely unsupported by
608 the author. Don't bug him with installation questions!>
609
610 =item B<fading:> I<number>
611
612 Fade the text by the given percentage when focus is lost; option B<-fade>.
613
614 =item B<fadeColor:> I<colour>
615
616 Fade to this colour, when fading is used (see B<fading:>). The default
617 colour is black; option B<-fadecolor>.
618
619 =item B<tintColor:> I<colour>
620
621 Tint the transparent background pixmap with the given colour; option
622 B<-tint>.
623
624 =item B<shading:> I<number>
625
626 Darken (0 .. 100) or lighten (-1 .. -100) the transparent background image
627 in addition to tinting it; option B<-sh>.
628
629 =item B<scrollColor:> I<colour>
630
631 Use the specified colour for the scrollbar [default #B2B2B2].
632
633 =item B<troughColor:> I<colour>
634
635 Use the specified colour for the scrollbar's trough area [default
636 #969696]. Only relevant for rxvt (non XTerm/NeXT) scrollbar.
637
638 =item B<borderColor:> I<colour>
639
640 The colour of the border around the text area and between the scrollbar
641 and the text.
642
643 =item B<backgroundPixmap:> I<file[;geom]>
644
645 Use the specified XPM file (note the `.xpm' extension is optional) for
646 the background and also optionally specify its scaling with a geometry
647 string B<WxH+X+Y>, in which B<"W" / "H"> specify the
648 horizontal/vertical scale (percent) and B<"X" / "Y"> locate the image
649 centre (percent). A scale of 0 displays the image with tiling. A scale
650 of 1 displays the image without any scaling. A scale of 2 to 9
651 specifies an integer number of images in that direction. No image will
652 be magnified beyond 10 times its original size. The maximum permitted
653 scale is 1000. [default 0x0+50+50]
654
655 =item B<path:> I<path>
656
657 Specify the colon-delimited search path for finding XPM files.
658
659 =item B<font:> I<fontlist>
660
661 Select the fonts to be used. This is a comma separated list of font names
662 that are checked in order when trying to find glyphs for characters. The
663 first font defines the cell size for characters; other fonts might be
664 smaller, but not (in general) larger. A (hopefully) reasonable default
665 font list is always appended to it; option B<-fn>.
666
667 Each font can either be a standard X11 core font (XLFD) name, with
668 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
669
670 In addition, each font can be prefixed with additional hints and
671 specifications enclosed in square brackets (C<[]>). The only available
672 hint currently is C<codeset=codeset-name>, and this is only used for Xft
673 fonts.
674
675 For example, this font resource
676
677 URxvt.font: 9x15bold,\
678 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
679 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
680 [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
681 xft:Code2000:antialias=false
682
683 specifies five fonts to be used. The first one is C<9x15bold> (actually
684 the iso8859-1 version of the second font), which is the base font (because
685 it is named first) and thus defines the character cell grid to be 9 pixels
686 wide and 15 pixels high.
687
688 The second font is just used to add additional unicode characters not in
689 the base font, likewise the third, which is unfortunately non-bold, but
690 the bold version of the font does contain less characters, so this is a
691 useful supplement.
692
693 The third font is an Xft font with aliasing turned off, and the characters
694 are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
695 contains other characters, but we are not interested in them.
696
697 The last font is a useful catch-all font that supplies most of the
698 remaining unicode characters.
699
700 =item B<boldFont:> I<fontlist>
701
702 =item B<italicFont:> I<fontlist>
703
704 =item B<boldItalicFont:> I<fontlist>
705
706 The font list to use for displaying B<bold>, I<italic> or B<< I<bold
707 italic> >> characters, respectively.
708
709 If specified and non-empty, then the syntax is the same as for the
710 B<font>-resource, and the given font list will be used as is, which makes
711 it possible to substitute completely different font styles for bold and
712 italic.
713
714 If unset (the default), a suitable font list will be synthesized by
715 "morphing" the normal text font list into the desired shape. If that is
716 not possible, replacement fonts of the desired shape will be tried.
717
718 If set, but empty, then this specific style is disabled and the normal
719 text font will being used for the given style.
720
721 =item B<intensityStyles:> I<boolean>
722
723 When font styles are not enabled, or this option is enabled (B<True>,
724 option B<-is>, the default), bold and italic font styles imply high
725 intensity foreground/background colours. Disabling this option (B<False>,
726 option B<+is>) disables this behaviour, the high intensity colours are not
727 reachable.
728
729 =item B<selectstyle:> I<mode>
730
731 Set mouse selection style to B<old> which is 2.20, B<oldword> which
732 is xterm style with 2.20 old word selection, or anything else which
733 gives xterm style selection. Only effective when the original (non-perl)
734 selection code is in use.
735
736 =item B<scrollstyle:> I<mode>
737
738 Set scrollbar style to B<rxvt>, B<plain>, B<next> or B<xterm>. B<plain> is
739 the author's favourite.
740
741 =item B<title:> I<string>
742
743 Set window title string, the default title is the command-line
744 specified after the B<-e> option, if any, otherwise the application
745 name; option B<-title>.
746
747 =item B<iconName:> I<string>
748
749 Set the name used to label the window's icon or displayed in an icon
750 manager window, it also sets the window's title unless it is explicitly
751 set; option B<-n>.
752
753 =item B<mapAlert:> I<boolean>
754
755 B<True>: de-iconify (map) on receipt of a bell character. B<False>: no
756 de-iconify (map) on receipt of a bell character [default].
757
758 =item B<urgentOnBell:> I<boolean>
759
760 B<True>: set the urgency hint for the wm on receipt of a bell character.
761 B<False>: do not set the urgency hint [default].
762
763 =item B<visualBell:> I<boolean>
764
765 B<True>: use visual bell on receipt of a bell character; option B<-vb>.
766 B<False>: no visual bell [default]; option B<+vb>.
767
768 =item B<loginShell:> I<boolean>
769
770 B<True>: start as a login shell by prepending a `-' to B<argv[0]> of
771 the shell; option B<-ls>. B<False>: start as a normal sub-shell
772 [default]; option B<+ls>.
773
774 =item B<utmpInhibit:> I<boolean>
775
776 B<True>: inhibit writing record into the system log file B<utmp>;
777 option B<-ut>. B<False>: write record into the system log file B<utmp>
778 [default]; option B<+ut>.
779
780 =item B<print-pipe:> I<string>
781
782 Specify a command pipe for vt100 printer [default I<lpr(1)>]. Use
783 B<Print> to initiate a screen dump to the printer and B<Ctrl-Print> or
784 B<Shift-Print> to include the scrollback as well.
785
786 The string will be interpreted as if typed into the shell as-is.
787
788 Example:
789
790 URxvt.print-pipe: cat > $(TMPDIR=$HOME mktemp urxvt.XXXXXX)
791
792 This creates a new file in your home directory with the screen contents
793 every time you hit C<Print>.
794
795 =item B<scrollBar:> I<boolean>
796
797 B<True>: enable the scrollbar [default]; option B<-sb>. B<False>:
798 disable the scrollbar; option B<+sb>.
799
800 =item B<scrollBar_right:> I<boolean>
801
802 B<True>: place the scrollbar on the right of the window; option B<-sr>.
803 B<False>: place the scrollbar on the left of the window; option B<+sr>.
804
805 =item B<scrollBar_floating:> I<boolean>
806
807 B<True>: display an rxvt scrollbar without a trough; option B<-st>.
808 B<False>: display an rxvt scrollbar with a trough; option B<+st>.
809
810 =item B<scrollBar_align:> I<mode>
811
812 Align the B<top>, B<bottom> or B<centre> [default] of the scrollbar
813 thumb with the pointer on middle button press/drag.
814
815 =item B<scrollTtyOutput:> I<boolean>
816
817 B<True>: scroll to bottom when tty receives output; option B<-si>.
818 B<False>: do not scroll to bottom when tty receives output; option
819 B<+si>.
820
821 =item B<scrollWithBuffer:> I<boolean>
822
823 B<True>: scroll with scrollback buffer when tty receives new lines (and
824 B<scrollTtyOutput> is False); option B<-sw>. B<False>: do not scroll
825 with scrollback buffer when tty receives new lines; option B<+sw>.
826
827 =item B<scrollTtyKeypress:> I<boolean>
828
829 B<True>: scroll to bottom when a non-special key is pressed. Special keys
830 are those which are intercepted by rxvt-unicode for special handling and
831 are not passed onto the shell; option B<-sk>. B<False>: do not scroll to
832 bottom when a non-special key is pressed; option B<+sk>.
833
834 =item B<saveLines:> I<number>
835
836 Save I<number> lines in the scrollback buffer [default 64]. This
837 resource is limited on most machines to 65535; option B<-sl>.
838
839 =item B<internalBorder:> I<number>
840
841 Internal border of I<number> pixels. This resource is limited to 100;
842 option B<-b>.
843
844 =item B<externalBorder:> I<number>
845
846 External border of I<number> pixels. This resource is limited to 100;
847 option B<-w>, B<-bw>, B<-borderwidth>.
848
849 =item B<borderLess:> I<boolean>
850
851 Set MWM hints to request a borderless window, i.e. if honoured by the
852 WM, the rxvt-unicode window will not have window decorations; option B<-bl>.
853
854 =item B<skipBuiltinGlyphs:> I<boolean>
855
856 Compile I<frills>: Disable the usage of the built-in block graphics/line
857 drawing characters and just rely on what the specified fonts provide. Use
858 this if you have a good font and want to use its block graphic glyphs;
859 option B<-sbg>.
860
861 =item B<termName:> I<termname>
862
863 Specifies the terminal type name to be set in the B<TERM> environment
864 variable; option B<-tn>.
865
866 =item B<linespace:> I<number>
867
868 Specifies number of lines (pixel height) to insert between each row of
869 the display [default 0]; option B<-lsp>.
870
871 =item B<meta8:> I<boolean>
872
873 B<True>: handle Meta (Alt) + keypress to set the 8th bit. B<False>:
874 handle Meta (Alt) + keypress as an escape prefix [default].
875
876 =item B<mouseWheelScrollPage:> I<boolean>
877
878 B<True>: the mouse wheel scrolls a page full. B<False>: the mouse wheel
879 scrolls five lines [default].
880
881 =item B<pastableTabs:> I<boolean>
882
883 B<True>: store tabs as wide characters. B<False>: interpret tabs as cursor
884 movement only; option C<-ptab>.
885
886 =item B<cursorBlink:> I<boolean>
887
888 B<True>: blink the cursor. B<False>: do not blink the cursor [default];
889 option B<-bc>.
890
891 =item B<pointerBlank:> I<boolean>
892
893 B<True>: blank the pointer when a key is pressed or after a set number
894 of seconds of inactivity. B<False>: the pointer is always visible
895 [default].
896
897 =item B<pointerColor:> I<colour>
898
899 Mouse pointer foreground colour.
900
901 =item B<pointerColor2:> I<colour>
902
903 Mouse pointer background colour.
904
905 =item B<pointerBlankDelay:> I<number>
906
907 Specifies number of seconds before blanking the pointer [default 2]. Use a
908 large number (e.g. C<987654321>) to effectively disable the timeout.
909
910 =item B<backspacekey:> I<string>
911
912 The string to send when the backspace key is pressed. If set to B<DEC>
913 or unset it will send B<Delete> (code 127) or, if shifted, B<Backspace>
914 (code 8) - which can be reversed with the appropriate DEC private mode
915 escape sequence.
916
917 =item B<deletekey:> I<string>
918
919 The string to send when the delete key (not the keypad delete key) is
920 pressed. If unset it will send the sequence traditionally associated
921 with the B<Execute> key.
922
923 =item B<cutchars:> I<string>
924
925 The characters used as delimiters for double-click word selection
926 (whitespace delimiting is added automatically if resource is given).
927
928 When the perl selection extension is in use (the default if compiled
929 in, see the @@RXVT_NAME@@perl(3) manpage), a suitable regex using these
930 characters will be created (if the resource exists, otherwise, no regex
931 will be created). In this mode, characters outside ISO-8859-1 can be used.
932
933 When the selection extension is not used, only ISO-8859-1 characters can
934 be used. If not specified, the built-in default is used:
935
936 B<< BACKSLASH `"'&()*,;<=>?@[]{|} >>
937
938 =item B<preeditType:> I<style>
939
940 B<OverTheSpot>, B<OffTheSpot>, B<Root>; option B<-pt>.
941
942 =item B<inputMethod:> I<name>
943
944 I<name> of inputMethod to use; option B<-im>.
945
946 =item B<imLocale:> I<name>
947
948 The locale to use for opening the IM. You can use an C<LC_CTYPE> of e.g.
949 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
950 input extension to be able to input japanese characters while staying in
951 another locale; option B<-imlocale>.
952
953 =item B<imFont:> I<fontset>
954
955 Specify the font-set used for XIM styles C<OverTheSpot> or
956 C<OffTheSpot>. It must be a standard X font set (XLFD patterns separated
957 by commas), i.e. it's not in the same format as the other font lists used
958 in @@RXVT_NAME@@. The default will be set-up to chose *any* suitable found
959 found, preferably one or two pixels differing in size to the base font.
960 option B<-imfont>.
961
962 =item B<tripleclickwords:> I<boolean>
963
964 Change the meaning of triple-click selection with the left mouse
965 button. Instead of selecting a full line it will extend the selection to
966 the end of the logical line only; option B<-tcw>.
967
968 =item B<insecure:> I<boolean>
969
970 Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
971 echo arbitrary strings like the icon name or the locale. This could be
972 abused if somebody gets 8-bit-clean access to your display, whether
973 through a mail client displaying mail bodies unfiltered or through
974 write(1) or any other means. Therefore, these sequences are disabled by
975 default. (Note that many other terminals, including xterm, have these
976 sequences enabled by default, which doesn't make it safer, though).
977
978 You can enable them by setting this boolean resource or specifying
979 B<-insecure> as an option. At the moment, this enables display-answer,
980 locale, findfont, icon label and window title requests.
981
982 =item B<modifier:> I<modifier>
983
984 Set the key to be interpreted as the Meta key to: B<alt>, B<meta>,
985 B<hyper>, B<super>, B<mod1>, B<mod2>, B<mod3>, B<mod4>, B<mod5>; option
986 B<-mod>.
987
988 =item B<answerbackString:> I<string>
989
990 Specify the reply rxvt-unicode sends to the shell when an ENQ (control-E)
991 character is passed through. It may contain escape values as described
992 in the entry on B<keysym> following.
993
994 =item B<secondaryScreen:> I<boolean>
995
996 Turn on/off secondary screen (default enabled).
997
998 =item B<secondaryScroll:> I<boolean>
999
1000 Turn on/off secondary screen scroll (default enabled). If this
1001 option is enabled, scrolls on the secondary screen will change the
1002 scrollback buffer and switching to/from the secondary screen will
1003 instead scroll the screen up.
1004
1005 =item B<hold>: I<boolean>
1006
1007 Turn on/off hold window after exit support. If enabled, @@RXVT_NAME@@
1008 will not immediately destroy its window when the program executed within
1009 it exits. Instead, it will wait till it is being killed or closed by the
1010 user.
1011
1012 =item B<keysym.>I<sym>: I<string>
1013
1014 Compile I<frills>: Associate I<string> with keysym I<sym>. The
1015 intervening resource name B<keysym.> cannot be omitted.
1016
1017 The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1018 any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1019 B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1020 and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1021 B<2>, B<3>, B<4>, B<5>.
1022
1023 The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1024 whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1025 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1026 current application keymap mode state.
1027
1028 The spellings of I<key> can be obtained by using B<xev>(1) command or
1029 searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1030 omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1031 keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1032 performed in an exact manner; however, the closest match is assured.
1033
1034 I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
1035 C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
1036 C<\000>: octal number) or verbatim control characters (C<^?>: delete,
1037 C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
1038 can start or end with whitespace. B<This feature is deprecated and will
1039 be removed>.
1040
1041 Please note that you need to double the C<\> in resource files, as
1042 Xlib itself does its own de-escaping (you can use C<\033> instead of
1043 C<\e> (and so on), which will work with both Xt and @@RXVT_NAME@@'s own
1044 processing).
1045
1046 You can define a range of keysyms in one shot by providing a I<string>
1047 with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1048 should be a character not used by the strings.
1049
1050 Its usage can be demonstrated by an example:
1051
1052 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1053
1054 The above line is equivalent to the following three lines:

1060 If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1061 is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1062 example the following means "change the current locale to C<zh_CN.GBK>
1063 when Control-Meta-c is being pressed":
1064
1065 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1066
1067 If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1068 is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1069 manpage. For example, the F<selection> extension (activated via
1070 C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1071
1072 URxvt.keysym.M-C-c: perl:selection:rot13
1073
1074 Due the the large number of modifier combinations, a defined key mapping
1075 will match if at I<at least> the specified identifiers are being set, and
1076 no other key mappings with those and more bits are being defined. That
1077 means that defining a key map for C<a> will automatically provide
1078 definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1079 mappings themselves.
1080
1081 Unfortunately, this will override built-in key mappings. For example
1082 if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1083 C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1084 user-defined keymap using the C<builtin:> replacement:
1085
1086 URxvt.keysym.Insert: <my insert key sequence>
1087 URxvt.keysym.S-Insert: builtin:
1088
1089 The first line defines a mapping for C<Insert> and I<any> combination
1090 of modifiers. The second line re-establishes the default mapping for
1091 C<Shift-Insert>.
1092
1093 The following example will map Control-Meta-1 and Control-Meta-2 to
1094 the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1095 font-switching at runtime:
1096
1097 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1098 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1099
1100 Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1101 info):
1102
1103 URxvt.keysym.M-C-3: command:\033[8;25;80t

1112
1113 Extension names can be prefixed with a C<-> sign to prohibit using
1114 them. This can be useful to selectively disable some extensions loaded
1115 by default, or specified via the C<perl-ext-common> resource. For
1116 example, C<default,-selection> will use all the default extension except
1117 C<selection>.
1118
1119 Extension names can also be followed by an argument in angle brackets
1120 (e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1121 searchable scrollback to Alt/Meta-s). Mentioning the same extension
1122 multiple times with different arguments will pass multiple arguments to
1123 the extension.
1124
1125 Each extension is looked up in the library directories, loaded if
1126 necessary, and bound to the current terminal instance.
1127
1128 If both of these resources are the empty string, then the perl
1129 interpreter will not be initialized. The idea behind two options is that
1130 B<perl-ext-common> will be used for extensions that should be available to

1181
1182 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
1183 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1184 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1185 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1186 arrows and its behaviour mimics that of I<xterm>
1187
1188 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
1189 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.

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

1238
1239 Changing fonts (or font sizes, respectively) via the keypad is not yet
1240 supported in rxvt-unicode. Bug me if you need this.
1241
1242 You can, however, switch fonts at runtime using escape sequences, e.g.:
1243
1244 printf '\e]710;%s\007' "9x15bold,xft:Kochi Gothic"
1245
1246 You can use keyboard shortcuts, too:
1247
1248 URxvt.keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
1249 URxvt.keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
1250
1251 rxvt-unicode will automatically re-apply these fonts to the output so far.
1252
1253 =head1 ISO 14755 SUPPORT
1254
1255 ISO 14755 is a standard for entering and viewing unicode characters
1256 and character codes using the keyboard. It consists of 4 parts. The
1257 first part is available rxvt-unicode has been compiled with
1258 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1259 with C<--enable-iso14755>.
1260
1261 =over 4
1262
1263 =item * 5.1: Basic method
1264
1265 This allows you to enter unicode characters using their hexcode.
1266
1267 Start by pressing and holding both C<Control> and C<Shift>, then enter
1268 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1269 commit the character as if it were typed directly. While holding down
1270 C<Control> and C<Shift> you can also enter multiple characters by pressing
1271 C<Space>, which will commit the current character and lets you start a new
1272 one.
1273
1274 As an example of use, imagine a business card with a japanese e-mail
1275 address, which you cannot type. Fortunately, the card has the e-mail
1276 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1277 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1278 followed by releasing the modifier keys.
1279
1280 =item * 5.2: Keyboard symbols entry method
1281
1282 This mode lets you input characters representing the keycap symbols of
1283 your keyboard, if representable in the current locale encoding.
1284
1285 Start by pressing C<Control> and C<Shift> together, then releasing
1286 them. The next special key (cursor keys, home etc.) you enter will not
1287 invoke its usual function but instead will insert the corresponding
1288 keycap symbol. The symbol will only be entered when the key has been
1289 released, otherwise pressing e.g. C<Shift> would enter the symbol for
1290 C<ISO Level 2 Switch>, although your intention might have been to enter a
1291 reverse tab (Shift-Tab).
1292
1293 =item * 5.3: Screen-selection entry method
1294
1295 While this is implemented already (it's basically the selection
1296 mechanism), it could be extended by displaying a unicode character map.
1297
1298 =item * 5.4: Feedback method for identifying displayed characters for later input
1299
1300 This method lets you display the unicode character code associated with
1301 characters already displayed.
1302
1303 You enter this mode by holding down C<Control> and C<Shift> together, then
1304 pressing and holding the left mouse button and moving around. The unicode
1305 hex code(s) (it might be a combining character) of the character under the
1306 pointer is displayed until you release C<Control> and C<Shift>.
1307
1308 In addition to the hex codes it will display the font used to draw this
1309 character - due to implementation reasons, characters combined with
1310 combining characters, line drawing characters and unknown characters will
1311 always be drawn using the built-in support font.

1320 B<@@RXVT_NAME@@> tries to write an entry into the I<utmp>(5) file so that
1321 it can be seen via the I<who(1)> command, and can accept messages. To

1325 =head1 COLORS AND GRAPHICS
1326
1327 In addition to the default foreground and background colours,
1328 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1329 high-intensity bold/blink versions of the same). Here is a list of the
1330 colours with their names.
1331
1332 =begin table
1333
1334 B<color0> (black) = Black
1335 B<color1> (red) = Red3
1336 B<color2> (green) = Green3
1337 B<color3> (yellow) = Yellow3
1338 B<color4> (blue) = Blue3
1339 B<color5> (magenta) = Magenta3
1340 B<color6> (cyan) = Cyan3
1341 B<color7> (white) = AntiqueWhite
1342 B<color8> (bright black) = Grey25
1343 B<color9> (bright red) = Red
1344 B<color10> (bright green) = Green
1345 B<color11> (bright yellow) = Yellow
1346 B<color12> (bright blue) = Blue
1347 B<color13> (bright magenta) = Magenta
1348 B<color14> (bright cyan) = Cyan
1349 B<color15> (bright white) = White
1350 B<foreground> = Black
1351 B<background> = White
1352
1353 =end table
1354
1355 It is also possible to specify the colour values of B<foreground>,
1356 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1357 a number 0-15, as a convenient shorthand to reference the colour name of
1358 color0-color15.
1359
1360 In addition to the colours defined above, @@RXVT_NAME@@ offers an
1361 additional 72 colours. The first 64 of those (with indices 16 to 79)
1362 consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
1363 16>), followed by 8 additional shades of gray (with indices 80 to 87).
1364
1365 Together, all those colours implement the 88 colour xterm colours. Only
1366 the first 16 can be changed using resources currently, the rest can only
1367 be changed via command sequences ("escape codes").
1368
1369 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1370 always swapping the foreground/background colours. This is in contrast to
1371 I<xterm>(1) where the colours are only swapped if they have not otherwise
1372 been specified. For example,
1373
1374 =over 4
1375
1376 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1377
1378 would yield White on Black, while on I<xterm>(1) it would yield Black
1379 on White.

1382
1383 =head2 ALPHA CHANNEL SUPPORT
1384
1385 If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1386 their act together, rxvt-unicode will support C<rgba:rrrr/gggg/bbbb/aaaa>
1387 (recommended, but B<MUST> have 4 digits/component) colour specifications,
1388 in addition to the ones provided by X, where the additional A component
1389 specifies opacity (alpha) values. The minimum value of C<0> is completely
1390 transparent). You can also prefix any color with C<[percent]>, where
1391 C<percent> is a decimal percentage (0-100) that specifies the opacity of
1392 the color, where C<0> is completely transparent and C<100> is completelxy
1393 opaque.
1394
1395 You probably need to specify B<"-depth 32">, too, and have the luck that
1396 your X-server uses ARGB pixel layout, as X is far from just supporting
1397 ARGB visuals out of the box, and rxvt-unicode just fudges around.
1398
1399 For example, the following selects an almost completely transparent red
1400 background, and an almost opaque pink foreground:
