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/*checkout*/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 left-to-right 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 userfriendly, 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 it's 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 it's predecessor, supports things such as XFT and ISO 14755 that are handy
52 in i18n-environments, is faster, and has a lot less bugs 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 it's 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) easier 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'.

84 The following options are available:

174 =item B<-fn> I<fontlist>
175
176 Select the fonts to be used. This is a comma separated list of font names
177 that are used in turn when trying to display Unicode characters. The
178 first font defines the cell size for characters; other fonts might be
179 smaller, but not (in general) larger. A (hopefully) reasonable default
180 font list is always appended to it. See resource B<font> for more details.
181
182 In short, to specify an X11 core font, just specify it's name or prefix it
183 with C<x:>. To specify an XFT-font, you need to prefix it with C<xft:>,
184 e.g.:

264 If enabled (default), "Horizontal Tab" characters are being stored as
265 actual wide characters in the screen buffer, which makes it possible to
266 select and paste them. Since a horizontal tab is a cursor movement and
267 not an actual glyph, this can sometimes be visually annoying as the cursor

322 failing that, I<sh(1)>.
323
324 Please note that you must specify a program with arguments. If you want to

394 =item B<-hold>|B<+hold>
395
396 Turn on/off hold window after exit support. If enabled, @@RXVT_NAME@@
397 will not immediately destroy its window when the program executed within
398 it exits. Instead, it will wait till it is being killed or closed by the
399 user; resource B<hold>.

402
403 Remap a key symbol. See resource B<keysym>.
404
405 =item B<-embed> I<windowid>
406
407 Tells @@RXVT_NAME@@ to embed it's windows into an already-existing window,
408 which enables applications to easily embed a terminal.
409
410 Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
411 shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
412 quite a bit, so don't expect it to keep some specific state. It's best to
413 create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
414
415 The window will not be destroyed when @@RXVT_NAME@@ exits.
416
417 It might be useful to know that @@RXVT_NAME@@ will not close file
418 descriptors passed to it (except for stdin/out/err, of course), so you
419 can use file descriptors to communicate with the programs within the
420 terminal. This works regardless of wether the C<-embed> option was used or
421 not.
422
423 Here is a short Gtk2-perl snippet that illustrates how this option can be
424 used (a longer example is in F<doc/embed>):
425
426 my $rxvt = new Gtk2::Socket;
427 $rxvt->signal_connect_after (realize => sub {
428 my $xid = $_[0]->window->get_xid;
429 system "@@RXVT_NAME@@ -embed $xid &";
430 });
431
432 =item B<-pty-fd> I<fileno>
433
434 Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
435 pair but instead use the given filehandle as the tty master. This is
436 useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
437 without having to run a program within it.
438
439 If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
440 entries and will not tinker with pty/tty permissions - you have to do that
441 yourself if you want that.
442
443 Here is a example in perl that illustrates how this option can be used (a
444 longer example is in F<doc/pty-fd>):
445
446 use IO::Pty;
447 use Fcntl;
448
449 my $pty = new IO::Pty;
450 fcntl $pty, F_SETFD, 0; # clear close-on-exec
451 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
452 close $pty;
453
454 # now communicate with rxvt
455 my $slave = $pty->slave;
456 while (<$slave>) { print $slave "got <$_>\n" }

463
464 =head1 RESOURCES (available also as long-options)
465
466 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
467 options) compiled into your version.
468
469 There are two different methods that @@RXVT_NAME@@ can use to get the
470 Xresource data: using the X libraries (Xrm*-functions) or internal
471 Xresources reader (B<~/.Xdefaults>). For the first method (ie.
472 B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
473 resources using X11 tools like B<xrdb>. Many distribution do also load
474 settings from the B<~/.Xresources> file when X starts. @@RXVT_NAME@@
475 will consult the following files/resources in order, with later settings
476 overwriting earlier ones:
477
478 1. system-wide app-defaults file, either locale-dependent OR global
479 2. app-defaults file in $XAPPLRESDIR
480 3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
481 4. SCREEN_RESOURCES for the current screen
482 5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
483
484 If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
485 lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
486 set in XAPPLOADDIR/URxvt (compile-time defined: usually
487 B</usr/lib/X11/app-defaults/URxvt>) and resources set in
488 B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
489 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
490 class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
491 resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
492 easily configured, while the class name B<URxvt> allows resources
493 unique to B<@@RXVT_NAME@@>, notably colours and key-handling, to be
494 shared between different B<@@RXVT_NAME@@> configurations. If no
495 resources are specified, suitable defaults will be used. Command-line
496 arguments can be used to override resource settings. The following
497 resources are allowed:
498
499 =over 4
500
501 =item B<geometry:> I<geom>
502
503 Create the window with the specified X window geometry [default 80x24];
504 option B<-geometry>.
505
506 =item B<background:> I<colour>
507
508 Use the specified colour as the window's background colour [default
509 White]; option B<-bg>.
510
511 =item B<foreground:> I<colour>
512
513 Use the specified colour as the window's foreground colour [default
514 Black]; option B<-fg>.
515
516 =item B<color>I<n>B<:> I<colour>
517
518 Use the specified colour for the colour value I<n>, where 0-7
519 corresponds to low-intensity (normal) colours and 8-15 corresponds to
520 high-intensity (bold = bright foreground, blink = bright background)
521 colours. The canonical names are as follows: 0=black, 1=red, 2=green,
522 3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
523 names used are listed in the B<COLORS AND GRAPHICS> section.
524
525 Colours higher than 15 cannot be set using resources (yet), but can be
526 changed using an escape command (see @@RXVT_NAME@@(7)).
527
528 Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
529 88 colour support). Colours 80-87 are evenly spaces grey steps.
530
531 =item B<colorBD:> I<colour>
532
533 =item B<colorIT:> I<colour>
534
535 Use the specified colour to display bold or italic characters when the
536 foreground colour is the default. If font styles are not available
537 (Compile I<styles>) and this option is unset, reverse video is used instead.
538
539 =item B<colorUL:> I<colour>
540
541 Use the specified colour to display underlined characters when the
542 foreground colour is the default.
543
544 =item B<colorRV:> I<colour>
545
546 Use the specified colour as the background for reverse video
547 characters.
548
549 =item B<underlineColor:> I<colour>
550
551 If set, use the specified colour as the colour for the underline
552 itself. If unset, use the foreground colour.
553
554 =item B<cursorColor:> I<colour>
555
556 Use the specified colour for the cursor. The default is to use the
557 foreground colour; option B<-cr>.
558
559 =item B<cursorColor2:> I<colour>
560
561 Use the specified colour for the colour of the cursor text. For this to
562 take effect, B<cursorColor> must also be specified. The default is to
563 use the background colour.
564
565 =item B<reverseVideo:> I<boolean>
566
567 B<True>: simulate reverse video by foreground and background colours;
568 option B<-rv>. B<False>: regular screen colours [default]; option
569 B<+rv>. See note in B<COLORS AND GRAPHICS> section.
570
571 =item B<jumpScroll:> I<boolean>
572
573 B<True>: specify that jump scrolling should be used. When scrolling
574 quickly, fewer screen updates are performed [default]; option B<-j>.
575 B<False>: specify that smooth scrolling should be used; option B<+j>.
576
577 =item B<inheritPixmap:> I<boolean>
578
579 B<True>: make the background inherit the parent windows' pixmap, giving
580 artificial transparency. B<False>: do not inherit the parent windows'
581 pixmap.
582
583 =item B<fading:> I<number>
584
585 Fade the text by the given percentage when focus is lost; option B<-fade>.
586
587 =item B<fadeColor:> I<colour>
588
589 Fade to this colour, when fading is used (see B<fading:>). The default
590 colour is black; option B<-fadecolor>.
591
592 =item B<tintColor:> I<colour>
593
594 Tint the transparent background pixmap with the given colour; option
595 B<-tint>.
596
597 =item B<shading:> I<number>
598
599 Darken (0 .. 100) or lighten (-1 .. -100) the transparent background
600 image in addition to tinting it.
601
602 =item B<scrollColor:> I<colour>
603
604 Use the specified colour for the scrollbar [default #B2B2B2].
605
606 =item B<troughColor:> I<colour>
607
608 Use the specified colour for the scrollbar's trough area [default
609 #969696]. Only relevant for rxvt (non XTerm/NeXT) scrollbar.
610
611 =item B<borderColor:> I<colour>
612
613 The colour of the border around the text area and between the scrollbar
614 and the text.
615
616 =item B<backgroundPixmap:> I<file[;geom]>
617
618 Use the specified XPM file (note the `.xpm' extension is optional) for
619 the background and also optionally specify its scaling with a geometry
620 string B<WxH+X+Y>, in which B<"W" / "H"> specify the
621 horizontal/vertical scale (percent) and B<"X" / "Y"> locate the image
622 centre (percent). A scale of 0 displays the image with tiling. A scale
623 of 1 displays the image without any scaling. A scale of 2 to 9
624 specifies an integer number of images in that direction. No image will
625 be magnified beyond 10 times its original size. The maximum permitted
626 scale is 1000. [default 0x0+50+50]
627
628 =item B<menu:> I<file[;tag]>
629
630 Read in the specified menu file (note the `.menu' extension is
631 optional) and also optionally specify a starting tag to find. See the
632 reference documentation for details on the syntax for the menuBar.
633
634 =item B<path:> I<path>
635
636 Specify the colon-delimited search path for finding files (XPM and
637 menus), in addition to the paths specified by the B<RXVTPATH> and
638 B<PATH> environment variables.
639
640 =item B<font:> I<fontlist>
641
642 Select the fonts to be used. This is a comma separated list of font
643 names that are used in turn when trying to display Unicode characters.
644 The first font defines the cell size for characters; other fonts might
645 be smaller, but not larger. A reasonable default font list is always
646 appended to it; option B<-fn>.
647
648 Each font can either be a standard X11 core font (XLFD) name, with
649 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
650
651 In addition, each font can be prefixed with additional hints and
652 specifications enclosed in square brackets (C<[]>). The only available
653 hint currently is C<codeset=codeset-name>, and this is only used for Xft
654 fonts.
655
656 For example, this font resource
657
658 URxvt*font: 9x15bold,\
659 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
660 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
661 [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
662 xft:Code2000:antialias=false
663
664 specifies five fonts to be used. The first one is C<9x15bold> (actually
665 the iso8859-1 version of the second font), which is the base font (because
666 it is named first) and thus defines the character cell grid to be 9 pixels
667 wide and 15 pixels high.
668
669 The second font is just used to add additional unicode characters not in
670 the base font, likewise the third, which is unfortunately non-bold, but
671 the bold version of the font does contain less characters, so this is a
672 useful supplement.
673
674 The third font is an Xft font with aliasing turned off, and the characters
675 are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
676 contains other characters, but we are not interested in them.
677
678 The last font is a useful catch-all font that supplies most of the
679 remaining unicode characters.
680
681 =item B<boldFont:> I<fontlist>
682
683 =item B<italicFont:> I<fontlist>
684
685 =item B<boldItalicFont:> I<fontlist>
686
687 The font list to use for displaying B<bold>, I<italic> or B<< I<bold
688 italic> >> characters, respectively.
689
690 If specified and non-empty, then the syntax is the same as for the
691 B<font>-resource, and the given font list will be used as is, which makes
692 it possible to substitute completely different font styles for bold and
693 italic.
694
695 If unset (the default), a suitable font list will be synthesized by
696 "morphing" the normal text font list into the desired shape. If that is
697 not possible, replacement fonts of the desired shape will be tried.
698
699 If set, but empty, then this specific style is disabled and the normal
700 text font will being used for the given style.
701
702 =item B<intensityStyles:> I<boolean>
703
704 When font styles are not enabled, or this option is enabled (B<True>,
705 option B<-is>, the default), bold and italic font styles imply high
706 intensity foreground/backround colours. Disabling this option (B<False>,
707 option B<+is>) disables this behaviour, the high intensity colours are not
708 reachable.
709
710 =item B<selectstyle:> I<mode>
711
712 Set mouse selection style to B<old> which is 2.20, B<oldword> which is
713 xterm style with 2.20 old word selection, or anything else which gives
714 xterm style selection.
715
716 =item B<scrollstyle:> I<mode>
717
718 Set scrollbar style to B<rxvt>, B<plain>, B<next> or B<xterm>. B<plain> is
719 the author's favourite.
720
721 =item B<title:> I<string>
722
723 Set window title string, the default title is the command-line
724 specified after the B<-e> option, if any, otherwise the application
725 name; option B<-title>.
726
727 =item B<iconName:> I<string>
728
729 Set the name used to label the window's icon or displayed in an icon
730 manager window, it also sets the window's title unless it is explicitly
731 set; option B<-n>.
732
733 =item B<mapAlert:> I<boolean>
734
735 B<True>: de-iconify (map) on receipt of a bell character. B<False>: no
736 de-iconify (map) on receipt of a bell character [default].
737
738 =item B<visualBell:> I<boolean>
739
740 B<True>: use visual bell on receipt of a bell character; option B<-vb>.
741 B<False>: no visual bell [default]; option B<+vb>.
742
743 =item B<loginShell:> I<boolean>
744
745 B<True>: start as a login shell by prepending a `-' to B<argv[0]> of
746 the shell; option B<-ls>. B<False>: start as a normal sub-shell
747 [default]; option B<+ls>.
748
749 =item B<utmpInhibit:> I<boolean>
750
751 B<True>: inhibit writing record into the system log file B<utmp>;
752 option B<-ut>. B<False>: write record into the system log file B<utmp>
753 [default]; option B<+ut>.
754
755 =item B<print-pipe:> I<string>
756
757 Specify a command pipe for vt100 printer [default I<lpr(1)>]. Use
758 B<Print> to initiate a screen dump to the printer and B<Ctrl-Print> or
759 B<Shift-Print> to include the scrollback as well.
760
761 The string will be interpreted as if typed into the shell as-is.
762
763 Example:
764
765 URxvt*print-pipe: cat > $(TMPDIR=$HOME mktemp urxvt.XXXXXX)
766
767 This creates a new file in your home directory with the screen contents
768 everytime you hit C<Print>.
769
770 =item B<scrollBar:> I<boolean>
771
772 B<True>: enable the scrollbar [default]; option B<-sb>. B<False>:
773 disable the scrollbar; option B<+sb>.
774
775 =item B<scrollBar_right:> I<boolean>
776
777 B<True>: place the scrollbar on the right of the window; option B<-sr>.
778 B<False>: place the scrollbar on the left of the window; option B<+sr>.
779
780 =item B<scrollBar_floating:> I<boolean>
781
782 B<True>: display an rxvt scrollbar without a trough; option B<-st>.
783 B<False>: display an rxvt scrollbar with a trough; option B<+st>.
784
785 =item B<scrollBar_align:> I<mode>
786
787 Align the B<top>, B<bottom> or B<centre> [default] of the scrollbar
788 thumb with the pointer on middle button press/drag.
789
790 =item B<scrollTtyOutput:> I<boolean>
791
792 B<True>: scroll to bottom when tty receives output; option B<-si>.
793 B<False>: do not scroll to bottom when tty receives output; option
794 B<+si>.
795
796 =item B<scrollWithBuffer:> I<boolean>
797
798 B<True>: scroll with scrollback buffer when tty receives new lines (and
799 B<scrollTtyOutput> is False); option B<-sw>. B<False>: do not scroll
800 with scrollback buffer when tty recieves new lines; option B<+sw>.
801
802 =item B<scrollTtyKeypress:> I<boolean>
803
804 B<True>: scroll to bottom when a non-special key is pressed. Special keys
805 are those which are intercepted by rxvt-unicode for special handling and
806 are not passed onto the shell; option B<-sk>. B<False>: do not scroll to
807 bottom when a non-special key is pressed; option B<+sk>.
808
809 =item B<saveLines:> I<number>
810
811 Save I<number> lines in the scrollback buffer [default 64]. This
812 resource is limited on most machines to 65535; option B<-sl>.
813
814 =item B<internalBorder:> I<number>
815
816 Internal border of I<number> pixels. This resource is limited to 100;
817 option B<-b>.
818
819 =item B<externalBorder:> I<number>
820
821 External border of I<number> pixels. This resource is limited to 100;
822 option B<-w>, B<-bw>, B<-borderwidth>.
823
824 =item B<borderLess:> I<boolean>
825
826 Set MWM hints to request a borderless window, i.e. if honoured by the
827 WM, the rxvt-unicode window will not have window decorations; option B<-bl>.
828
829 =item B<termName:> I<termname>
830
831 Specifies the terminal type name to be set in the B<TERM> environment
832 variable; option B<-tn>.
833
834 =item B<linespace:> I<number>
835
836 Specifies number of lines (pixel height) to insert between each row of
837 the display [default 0]; option B<-lsp>.
838
839 =item B<meta8:> I<boolean>
840
841 B<True>: handle Meta (Alt) + keypress to set the 8th bit. B<False>:
842 handle Meta (Alt) + keypress as an escape prefix [default].
843
844 =item B<mouseWheelScrollPage:> I<boolean>
845
846 B<True>: the mouse wheel scrolls a page full. B<False>: the mouse wheel
847 scrolls five lines [default].
848
849 =item B<pastableTabs:> I<boolean>
850
851 B<True>: store tabs as wide characters. B<False>: interpret tabs as cursor
852 movement only; option C<-ptab>.
853
854 =item B<cursorBlink:> I<boolean>
855
856 B<True>: blink the cursor. B<False>: do not blink the cursor [default];
857 option B<-bc>.
858
859 =item B<pointerBlank:> I<boolean>
860
861 B<True>: blank the pointer when a key is pressed or after a set number
862 of seconds of inactivity. B<False>: the pointer is always visible
863 [default].
864
865 =item B<pointerColor:> I<colour>
866
867 Mouse pointer foreground colour.
868
869 =item B<pointerColor2:> I<colour>
870
871 Mouse pointer background colour.
872
873 =item B<pointerBlankDelay:> I<number>
874
875 Specifies number of seconds before blanking the pointer [default 2]. Use a
876 large number (e.g. C<987654321>) to effectively disable the timeout.
877
878 =item B<backspacekey:> I<string>
879
880 The string to send when the backspace key is pressed. If set to B<DEC>
881 or unset it will send B<Delete> (code 127) or, if shifted, B<Backspace>
882 (code 8) - which can be reversed with the appropriate DEC private mode
883 escape sequence.
884
885 =item B<deletekey:> I<string>
886
887 The string to send when the delete key (not the keypad delete key) is
888 pressed. If unset it will send the sequence traditionally associated
889 with the B<Execute> key.
890
891 =item B<cutchars:> I<string>
892
893 The characters used as delimiters for double-click word selection. The
894 built-in default:
895
896 B<< BACKSLASH `"'&()*,;<=>?@[]{|} >>
897
898 =item B<preeditType:> I<style>
899
900 B<OverTheSpot>, B<OffTheSpot>, B<Root>; option B<-pt>.
901
902 =item B<inputMethod:> I<name>
903
904 I<name> of inputMethod to use; option B<-im>.
905
906 =item B<imLocale:> I<name>
907
908 The locale to use for opening the IM. You can use an C<LC_CTYPE> of e.g.
909 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
910 input extension to be able to input japanese characters while staying in
911 another locale; option B<-imlocale>.
912
913 =item B<imFont:> I<fontset>
914
915 Specify the font-set used for XIM styles C<OverTheSpot> or
916 C<OffTheSpot>. It must be a standard X font set (XLFD patterns separated
917 by commas), i.e. it's not in the same format as the other font lists used
918 in @@RXVT_NAME@@. The default will be set-up to chose *any* suitable found
919 found, preferably one or two pixels differing in size to the base font.
920 option B<-imfont>.
921
922 =item B<tripleclickwords:> I<boolean>
923
924 Change the meaning of triple-click selection with the left mouse
925 button. Instead of selecting a full line it will extend the selection to
926 the end of the logical line only; option B<-tcw>.
927
928 =item B<insecure:> I<boolean>
929
930 Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
931 echo arbitrary strings like the icon name or the locale. This could be
932 abused if somebody gets 8-bit-clean access to your display, whether
933 through a mail client displaying mail bodies unfiltered or through
934 write(1) or any other means. Therefore, these sequences are disabled by
935 default. (Note that many other terminals, including xterm, have these
936 sequences enabled by default, which doesn't make it safer, though).
937
938 You can enable them by setting this boolean resource or specifying
939 B<-insecure> as an option. At the moment, this enables display-answer,
940 locale, findfont, icon label and window title requests as well as dynamic
941 menubar dispatch.
942
943 =item B<modifier:> I<modifier>
944
945 Set the key to be interpreted as the Meta key to: B<alt>, B<meta>,
946 B<hyper>, B<super>, B<mod1>, B<mod2>, B<mod3>, B<mod4>, B<mod5>; option
947 B<-mod>.
948
949 =item B<answerbackString:> I<string>
950
951 Specify the reply rxvt-unicode sends to the shell when an ENQ (control-E)
952 character is passed through. It may contain escape values as described
953 in the entry on B<keysym> following.
954
955 =item B<secondaryScreen:> I<bool>
956
957 Turn on/off secondary screen (default enabled).
958
959 =item B<secondaryScroll:> I<bool>
960
961 Turn on/off secondary screen scroll (default enabled). If the this
962 option is enabled, scrolls on the secondary screen will change the
963 scrollback buffer and switching to/from the secondary screen will
964 instead scroll the screen up.
965
966 =item B<hold>: I<bool>
967
968 Turn on/off hold window after exit support. If enabled, @@RXVT_NAME@@
969 will not immediately destroy its window when the program executed within
970 it exits. Instead, it will wait till it is being killed or closed by the
971 user.
972
973 =item B<keysym.>I<sym>: I<string>
974
975 Compile I<frills>: Associate I<string> with keysym I<sym>. The
976 intervening resource name B<keysym.> cannot be omitted.
977
978 The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
979 any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
980 B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
981 and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
982 B<2>, B<3>, B<4>, B<5>.
983
984 The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
985 whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
986 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
987 current application keymap mode state.
988
989 The spellings of I<key> can be obtained by using B<xev>(1) command or
990 searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
991 omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
992 keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
993 performed in an exact manner; however, the closest match is assured.
994
995 I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
996 C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
997 C<\000>: octal number) or verbatim control characters (C<^?>: delete,
998 C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
999 can start or end with whitespace.
1000
1001 Please note that you need to double the C<\> when using
1002 C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
1003 use C<\033> instead of C<\e> (and so on), which will work with both Xt and
1004 @@RXVT_NAME@@'s own processing).
1005
1006 You can define a range of keysyms in one shot by providing a I<string>
1007 with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
1008 should be a character not used by the strings.
1009
1010 Its usage can be demonstrated by an example:
1011
1012 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1013
1014 The above line is equivalent to the following three lines:
1015
1016 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1017 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1018 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1019
1020 If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1021 is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1022 example the following means "change the current locale to C<zh_CN.GBK>
1023 when Control-Meta-c is being pressed":
1024
1025 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1026
1027 If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1028 is passed to the C<on_keyboard_command> perl handler. See the @@RXVT_NAME@@perl(3)
1029 manpage. For example, the F<selection> extension (activated via
1030 C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1031
1032 URxvt.keysym.M-C-c: perl:selection:rot13
1033
1034 Due the the large number of modifier combinations, a defined key mapping
1035 will match if at I<at least> the specified identifiers are being set, and
1036 no other key mappings with those and more bits are being defined. That
1037 means that defining a key map for C<a> will automatically provide
1038 definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1039 mappings themselves.
1040
1041 Unfortunately, this will override built-in key mappings. For example
1042 if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1043 C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1044 user-defined keymap using the C<builtin:> replacement:
1045
1046 URxvt.keysym.Insert: <my insert key sequence>
1047 URxvt.keysym.S-Insert: builtin:
1048
1049 The first line defines a mapping for C<Insert> and I<any> combination
1050 of modifiers. The second line re-establishes the default mapping for
1051 C<Shift-Insert>.
1052
1053 The following example will map Control-Meta-1 and Control-Meta-2 to
1054 the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1055 font-switching at runtime:
1056

1058 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007

1088 =head1 THE SCROLLBAR
1089
1090 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
1091 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1092 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1093 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1094 arrows and its behaviour mimics that of I<xterm>
1095
1096 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
1097 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.
1098 Continuous scroll with B<Button2>.
1099
1100 =head1 MOUSE REPORTING
1101
1102 To temporarily override mouse reporting, for either the scrollbar or
1103 the normal text selection/insertion, hold either the Shift or the Meta
1104 (Alt) key while performing the desired mouse action.
1105
1106 If mouse reporting mode is active, the normal scrollbar actions are
1107 disabled -- on the assumption that we are using a fullscreen
1108 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1109 (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the
1110 up and down arrows sends B<ESC [ A> (Up) and B<ESC [ B> (Down),
1111 respectively.
1112
1113 =head1 TEXT SELECTION AND INSERTION

1124 to select a word; Left triple-click to select the entire logical line
1125 (which can span multiple screen lines), unless modified by resource
1126 B<tripleclickwords>.
1127
1128 Starting a selection while pressing the B<Meta> key (or B<Meta+Ctrl> keys)
1129 (Compile: I<frills>) will create a rectangular selection instead of a
1130 normal one. In this mode, every selected row becomes its own line in the
1131 selection, and trailing whitespace is visually underlined and removed from
1132 the selection.
1133
1134 =item B<Insertion>:
1135
1136 Pressing and releasing the Middle mouse button (or B<Shift-Insert>) in

1138 inserted as if it had been typed on the keyboard.

1142 =head1 CHANGING FONTS
1143
1144 Changing fonts (or font sizes, respectively) via the keypad is not yet
1145 supported in rxvt-unicode. Bug me if you need this.
1146
1147 You can, however, switch fonts at runtime using escape sequences (and
1148 therefore using the menubar), e.g.:
1149
1150 printf '\e]710;%s\007' "9x15bold,xft:Kochi Gothic"
1151
1152 rxvt-unicode will automatically re-apply these fonts to the output so far.
1153
1154 =head1 ISO 14755 SUPPORT
1155
1156 ISO 14755 is a standard for entering and viewing unicode characters
1157 and character codes using the keyboard. It consists of 4 parts. The
1158 first part is available rxvt-unicode has been compiled with
1159 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1160 with C<--enable-iso14755>.
1161
1162 =over 4
1163
1164 =item * 5.1: Basic method
1165
1166 This allows you to enter unicode characters using their hexcode.
1167
1168 Start by pressing and holding both C<Control> and C<Shift>, then enter
1169 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1170 commit the character as if it were typed directly. While holding down
1171 C<Control> and C<Shift> you can also enter multiple characters by pressing
1172 C<Space>, which will commit the current character and lets you start a new
1173 one.
1174
1175 As an example of use, imagine a business card with a japanese e-mail
1176 address, which you cannot type. Fortunately, the card has the e-mail
1177 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1178 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1179 followed by releasing the modifier keys.
1180
1181 =item * 5.2: Keyboard symbols entry method
1182
1183 This mode lets you input characters representing the keycap symbols of
1184 your keyboard, if representable in the current locale encoding.
1185
1186 Start by pressing C<Control> and C<Shift> together, then releasing
1187 them. The next special key (cursor keys, home etc.) you enter will not
1188 invoke it's usual function but instead will insert the corresponding
1189 keycap symbol. The symbol will only be entered when the key has been
1190 released, otherwise pressing e.g. C<Shift> would enter the symbol for
1191 C<ISO Level 2 Switch>, although your intention might have been to enter a
1192 reverse tab (Shift-Tab).
1193
1194 =item * 5.3: Screen-selection entry method
1195
1196 While this is implemented already (it's basically the selection
1197 mechanism), it could be extended by displaying a unicode character map.
1198
1199 =item * 5.4: Feedback method for identifying displayed characters for later input
1200
1201 This method lets you display the unicode character code associated with
1202 characters already displayed.
1203
1204 You enter this mode by holding down C<Control> and C<Shift> together, then
1205 pressing and holding the left mouse button and moving around. The unicode
1206 hex code(s) (it might be a combining character) of the character under the
1207 pointer is displayed until you release C<Control> and C<Shift>.
1208
1209 In addition to the hex codes it will display the font used to draw this
1210 character - due to implementation reasons, characters combined with
1211 combining characters, line drawing characters and unknown characters will
1212 always be drawn using the built-in support font.

1228 In addition to the default foreground and background colours,
1229 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1230 high-intensity bold/blink versions of the same). Here is a list of the
1231 colours with their B<rgb.txt> names.

1247 B<color12> (bright blue) = Blue
1248 B<color13> (bright magenta) = Magenta
1249 B<color14> (bright cyan) = Cyan
1250 B<color15> (bright white) = White
1251 B<foreground> = Black
1252 B<background> = White
1253
1254 =end table
1255
1256 It is also possible to specify the colour values of B<foreground>,
1257 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1258 a number 0-15, as a convenient shorthand to reference the colour name of
1259 color0-color15.
1260
1261 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1262 always swapping the foreground/background colours. This is in contrast to
1263 I<xterm>(1) where the colours are only swapped if they have not otherwise
1264 been specified. For example,
1265
1266 =over 4
1267
1268 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1269
1270 would yield White on Black, while on I<xterm>(1) it would yield Black

1297 used), C<bg> is the colour code used as default background colour (or the
1298 string C<default>), and C<xpm> is the string C<default> if @@RXVT_NAME@@
1299 was compiled with XPM support. Libraries like C<ncurses> and C<slang> can
