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:

129 transparency is enabled with B<-tr> or B<-ip>. This only works for
130 non-tiled backgrounds, currently. See also the B<-sh> option that can be
131 used to brighten or darken the image in addition to tinting it; resource

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.:

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

317 Run the command with its command-line arguments in the B<@@RXVT_NAME@@>
318 window; also sets the window title and icon name to be the basename of
319 the program being executed if neither I<-title> (I<-T>) nor I<-n> are

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

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

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

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

1059 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007

1091 =head1 THE SCROLLBAR
1092
1093 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
1094 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1095 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1096 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1097 arrows and its behaviour mimics that of I<xterm>
1098
1099 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
1100 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.
1101 Continuous scroll with B<Button2>.
1102
1103 =head1 MOUSE REPORTING
1104
1105 To temporarily override mouse reporting, for either the scrollbar or
1106 the normal text selection/insertion, hold either the Shift or the Meta
1107 (Alt) key while performing the desired mouse action.
1108
1109 If mouse reporting mode is active, the normal scrollbar actions are
1110 disabled -- on the assumption that we are using a fullscreen
1111 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1112 (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the
1113 up and down arrows sends B<ESC [ A> (Up) and B<ESC [ B> (Down),
1114 respectively.
1115
1116 =head1 TEXT SELECTION AND INSERTION

1127 to select a word; Left triple-click to select the entire logical line
1128 (which can span multiple screen lines), unless modified by resource
1129 B<tripleclickwords>.
1130
1131 Starting a selection while pressing the B<Meta> key (or B<Meta+Ctrl> keys)
1132 (Compile: I<frills>) will create a rectangular selection instead of a
1133 normal one. In this mode, every selected row becomes its own line in the
1134 selection, and trailing whitespace is visually underlined and removed from
1135 the selection.
1136
1137 =item B<Insertion>:
1138
1139 Pressing and releasing the Middle mouse button (or B<Shift-Insert>) in
1140 an B<@@RXVT_NAME@@> window causes the current text selection to be
1141 inserted as if it had been typed on the keyboard.

1145 =head1 CHANGING FONTS
1146
1147 Changing fonts (or font sizes, respectively) via the keypad is not yet
1148 supported in rxvt-unicode. Bug me if you need this.
1149
1150 You can, however, switch fonts at runtime using escape sequences (and
1151 therefore using the menubar), e.g.:
1152
1153 printf '\e]710;%s\007' "9x15bold,xft:Kochi Gothic"
1154
1155 rxvt-unicode will automatically re-apply these fonts to the output so far.
1156
1157 =head1 ISO 14755 SUPPORT
1158
1159 ISO 14755 is a standard for entering and viewing unicode characters
1160 and character codes using the keyboard. It consists of 4 parts. The
1161 first part is available rxvt-unicode has been compiled with
1162 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1163 with C<--enable-iso14755>.
1164
1165 =over 4
1166
1167 =item * 5.1: Basic method
1168
1169 This allows you to enter unicode characters using their hexcode.
1170
1171 Start by pressing and holding both C<Control> and C<Shift>, then enter
1172 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1173 commit the character as if it were typed directly. While holding down
1174 C<Control> and C<Shift> you can also enter multiple characters by pressing
1175 C<Space>, which will commit the current character and lets you start a new
1176 one.
1177
1178 As an example of use, imagine a business card with a japanese e-mail
1179 address, which you cannot type. Fortunately, the card has the e-mail
1180 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1181 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1182 followed by releasing the modifier keys.
1183
1184 =item * 5.2: Keyboard symbols entry method
1185
1186 This mode lets you input characters representing the keycap symbols of
1187 your keyboard, if representable in the current locale encoding.
1188
1189 Start by pressing C<Control> and C<Shift> together, then releasing
1190 them. The next special key (cursor keys, home etc.) you enter will not
1191 invoke it's usual function but instead will insert the corresponding
1192 keycap symbol. The symbol will only be entered when the key has been
1193 released, otherwise pressing e.g. C<Shift> would enter the symbol for
1194 C<ISO Level 2 Switch>, although your intention might have been to enter a
1195 reverse tab (Shift-Tab).
1196
1197 =item * 5.3: Screen-selection entry method
1198
1199 While this is implemented already (it's basically the selection
1200 mechanism), it could be extended by displaying a unicode character map.
1201
1202 =item * 5.4: Feedback method for identifying displayed characters for later input
1203
1204 This method lets you display the unicode character code associated with
1205 characters already displayed.
1206
1207 You enter this mode by holding down C<Control> and C<Shift> together, then
1208 pressing and holding the left mouse button and moving around. The unicode
1209 hex code(s) (it might be a combining character) of the character under the
1210 pointer is displayed until you release C<Control> and C<Shift>.
1211
1212 In addition to the hex codes it will display the font used to draw this
1213 character - due to implementation reasons, characters combined with
1214 combining characters, line drawing characters and unknown characters will
1215 always be drawn using the built-in support font.

1229 =head1 COLORS AND GRAPHICS
1230
1231 In addition to the default foreground and background colours,
1232 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1233 high-intensity bold/blink versions of the same). Here is a list of the
1234 colours with their B<rgb.txt> names.
1235
1236 =begin table

1239 B<color1> (red) = Red3

1242 B<color4> (blue) = Blue3
1243 B<color5> (magenta) = Magenta3
1244 B<color6> (cyan) = Cyan3
1245 B<color7> (white) = AntiqueWhite
1246 B<color8> (bright black) = Grey25
1247 B<color9> (bright red) = Red
1248 B<color10> (bright green) = Green
1249 B<color11> (bright yellow) = Yellow
1250 B<color12> (bright blue) = Blue
1251 B<color13> (bright magenta) = Magenta
1252 B<color14> (bright cyan) = Cyan
1253 B<color15> (bright white) = White
1254 B<foreground> = Black
1255 B<background> = White
1256
1257 =end table
1258
1259 It is also possible to specify the colour values of B<foreground>,
1260 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1261 a number 0-15, as a convenient shorthand to reference the colour name of
1262 color0-color15.
1263
1264 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1265 always swapping the foreground/background colours. This is in contrast to
1266 I<xterm>(1) where the colours are only swapped if they have not otherwise
1267 been specified. For example,
1268
1269 =over 4
1270
1271 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1272
1273 would yield White on Black, while on I<xterm>(1) it would yield Black
1274 on White.

1299 C<default> to indicate that the default-colour escape sequence is to be
1300 used), C<bg> is the colour code used as default background colour (or the
1301 string C<default>), and C<xpm> is the string C<default> if @@RXVT_NAME@@
1302 was compiled with XPM support. Libraries like C<ncurses> and C<slang> can
