7 B<@@RXVT_NAME@@> [options] [-e command [ args ]]
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'.
83
84 The following options are available:

128 Tint the transparent background pixmap with the given colour when
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.:

263
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
268 on a tab character is displayed as a wide cursor; resource B<pastableTabs>.

308
309 This option specifies the name of the terminal type to be set in the
310 B<TERM> environment variable. This terminal type must exist in the
311 I<termcap(5)> database and should have I<li#> and I<co#> entries;
312 resource B<termName>.

316 Run the command with its command-line arguments in the B<@@RXVT_NAME@@>
317 window; also sets the window title and icon name to be the basename of
318 the program being executed if neither I<-title> (I<-T>) nor I<-n> are
319 given on the command line. If this option is used, it must be the last
320 on the command-line. If there is no B<-e> option then the default is to
321 run the program specified by the B<SHELL> environment variable or,
322 failing that, I<sh(1)>.
323
324 Please note that you must specify a program with arguments. If you want to
325 run shell commands, you have to specify the shell, like this:

357 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
358 input extension to be able to input japanese characters while staying in
359 another locale. resource B<imLocale>.

393
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>.
400
401 =item B<-keysym.>I<sym> I<string>
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" }

460 =head1 RESOURCES (available also as long-options)
461
462 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
463 options) compiled into your version.
464
465 There are two different methods that @@RXVT_NAME@@ can use to get the
466 Xresource data: using the X libraries (Xrm*-functions) or internal
467 Xresources reader (B<~/.Xdefaults>). For the first method (ie.
468 B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
469 resources using X11 tools like B<xrdb>. Many distribution do also load
470 settings from the B<~/.Xresources> file when X starts. @@RXVT_NAME@@
471 will consult the following files/resources in order, with later settings
472 overwriting earlier ones:
473
474 1. system-wide app-defaults file, either locale-dependent OR global
475 2. app-defaults file in $XAPPLRESDIR
476 3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
477 4. SCREEN_RESOURCES for the current screen
478 5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
479
480 If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
481 lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
482 set in XAPPLOADDIR/URxvt (compile-time defined: usually
483 B</usr/lib/X11/app-defaults/URxvt>) and resources set in
484 B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
485 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
486 class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
487 resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
488 easily configured, while the class name B<URxvt> allows resources
489 unique to B<@@RXVT_NAME@@>, notably colours and key-handling, to be
490 shared between different B<@@RXVT_NAME@@> configurations. If no
491 resources are specified, suitable defaults will be used. Command-line
492 arguments can be used to override resource settings. The following
493 resources are allowed:
494
495 =over 4
496
497 =item B<geometry:> I<geom>
498
499 Create the window with the specified X window geometry [default 80x24];
500 option B<-geometry>.
501
502 =item B<background:> I<colour>
503
504 Use the specified colour as the window's background colour [default
505 White]; option B<-bg>.
506
507 =item B<foreground:> I<colour>
508
509 Use the specified colour as the window's foreground colour [default
510 Black]; option B<-fg>.
511
512 =item B<color>I<n>B<:> I<colour>
513
514 Use the specified colour for the colour value I<n>, where 0-7
515 corresponds to low-intensity (normal) colours and 8-15 corresponds to
516 high-intensity (bold = bright foreground, blink = bright background)
517 colours. The canonical names are as follows: 0=black, 1=red, 2=green,
518 3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
519 names used are listed in the B<COLORS AND GRAPHICS> section.
520
521 Colours higher than 15 cannot be set using resources (yet), but can be
522 changed using an escape command (see @@RXVT_NAME@@(7)).
523
524 Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
525 88 colour support). Colours 80-87 are evenly spaces grey steps.
526
527 =item B<colorBD:> I<colour>
528
529 =item B<colorIT:> I<colour>
530
531 Use the specified colour to display bold or italic characters when the
532 foreground colour is the default. If font styles are not available
533 (Compile I<styles>) and this option is unset, reverse video is used instead.

552 Use the specified colour for the cursor. The default is to use the
553 foreground colour; option B<-cr>.
554
555 =item B<cursorColor2:> I<colour>
556
557 Use the specified colour for the colour of the cursor text. For this to
558 take effect, B<cursorColor> must also be specified. The default is to
559 use the background colour.
560
561 =item B<reverseVideo:> I<boolean>
562
563 B<True>: simulate reverse video by foreground and background colours;
564 option B<-rv>. B<False>: regular screen colours [default]; option

566
567 =item B<jumpScroll:> I<boolean>
568
569 B<True>: specify that jump scrolling should be used. When scrolling
570 quickly, fewer screen updates are performed [default]; option B<-j>.
571 B<False>: specify that smooth scrolling should be used; option B<+j>.
572
573 =item B<inheritPixmap:> I<boolean>
574
575 B<True>: make the background inherit the parent windows' pixmap, giving
576 artificial transparency. B<False>: do not inherit the parent windows'
577 pixmap.
578
579 =item B<fading:> I<number>

606
607 =item B<borderColor:> I<colour>
608
609 The colour of the border around the text area and between the scrollbar
610 and the text.
611
612 =item B<backgroundPixmap:> I<file[;geom]>
613
614 Use the specified XPM file (note the `.xpm' extension is optional) for
615 the background and also optionally specify its scaling with a geometry
616 string B<WxH+X+Y>, in which B<"W" / "H"> specify the
617 horizontal/vertical scale (percent) and B<"X" / "Y"> locate the image
618 centre (percent). A scale of 0 displays the image with tiling. A scale
619 of 1 displays the image without any scaling. A scale of 2 to 9
620 specifies an integer number of images in that direction. No image will
621 be magnified beyond 10 times its original size. The maximum permitted
622 scale is 1000. [default 0x0+50+50]
623
624 =item B<menu:> I<file[;tag]>
625
626 Read in the specified menu file (note the `.menu' extension is
627 optional) and also optionally specify a starting tag to find. See the
628 reference documentation for details on the syntax for the menuBar.
629
630 =item B<path:> I<path>
631
632 Specify the colon-delimited search path for finding files (XPM and
633 menus), in addition to the paths specified by the B<RXVTPATH> and
634 B<PATH> environment variables.
635
636 =item B<font:> I<fontlist>
637
638 Select the fonts to be used. This is a comma separated list of font
639 names that are used in turn when trying to display Unicode characters.
640 The first font defines the cell size for characters; other fonts might
641 be smaller, but not larger. A reasonable default font list is always
642 appended to it. option B<-fn>.
643
644 Each font can either be a standard X11 core font (XLFD) name, with
645 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
646
647 In addition, each font can be prefixed with additional hints and
648 specifications enclosed in square brackets (C<[]>). The only available
649 hint currently is C<codeset=codeset-name>, and this is only used for Xft
650 fonts.
651
652 For example, this font resource
653
654 URxvt*font: 9x15bold,\
655 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
656 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
657 [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
658 xft:Code2000:antialias=false
659
660 specifies five fonts to be used. The first one is C<9x15bold> (actually
661 the iso8859-1 version of the second font), which is the base font (because
662 it is named first) and thus defines the character cell grid to be 9 pixels
663 wide and 15 pixels high.
664
665 The second font is just used to add additional unicode characters not in
666 the base font, likewise the third, which is unfortunately non-bold, but
667 the bold version of the font does contain less characters, so this is a
668 useful supplement.
669
670 The third font is an Xft font with aliasing turned off, and the characters
671 are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
672 contains other characters, but we are not interested in them.
673
674 The last font is a useful catch-all font that supplies most of the
675 remaining unicode characters.
676
677 =item B<boldFont:> I<fontlist>
678
679 =item B<italicFont:> I<fontlist>
680
681 =item B<boldItalicFont:> I<fontlist>
682
683 The font list to use for displaying B<bold>, I<italic> or B<< I<bold
684 italic> >> characters, respectively.
685
686 If specified and non-empty, then the syntax is the same as for the
687 B<font>-resource, and the given font list will be used as is, which makes
688 it possible to substitute completely different font styles for bold and
689 italic.
690
691 If unset (the default), a suitable font list will be synthesized by
692 "morphing" the normal text font list into the desired shape. If that is
693 not possible, replacement fonts of the desired shape will be tried.
694
695 If set, but empty, then this specific style is disabled and the normal
696 text font will being used for the given style.
697
698 =item B<intensityStyles:> I<boolean>
699
700 When font styles are not enabled, or this option is enabled (B<True>,
701 option B<-is>, the default), bold and italic font styles imply high
702 intensity foreground/backround colours. Disabling this option (B<False>,
703 option B<+is>) disables this behaviour, the high intensity colours are not
704 reachable.
705
706 =item B<selectstyle:> I<mode>
707
708 Set mouse selection style to B<old> which is 2.20, B<oldword> which is
709 xterm style with 2.20 old word selection, or anything else which gives
710 xterm style selection.
711
712 =item B<scrollstyle:> I<mode>
713
714 Set scrollbar style to B<rxvt>, B<plain>, B<next> or B<xterm>. B<plain> is
715 the author's favourite.
716
717 =item B<title:> I<string>
718
719 Set window title string, the default title is the command-line
720 specified after the B<-e> option, if any, otherwise the application
721 name; option B<-title>.
722
723 =item B<iconName:> I<string>
724
725 Set the name used to label the window's icon or displayed in an icon
726 manager window, it also sets the window's title unless it is explicitly
727 set; option B<-n>.
728
729 =item B<mapAlert:> I<boolean>
730
731 B<True>: de-iconify (map) on receipt of a bell character. B<False>: no
732 de-iconify (map) on receipt of a bell character [default].
733
734 =item B<visualBell:> I<boolean>
735
736 B<True>: use visual bell on receipt of a bell character; option B<-vb>.
737 B<False>: no visual bell [default]; option B<+vb>.
738
739 =item B<loginShell:> I<boolean>
740
741 B<True>: start as a login shell by prepending a `-' to B<argv[0]> of
742 the shell; option B<-ls>. B<False>: start as a normal sub-shell

744
745 =item B<utmpInhibit:> I<boolean>
746
747 B<True>: inhibit writing record into the system log file B<utmp>;
748 option B<-ut>. B<False>: write record into the system log file B<utmp>
749 [default]; option B<+ut>.
750
751 =item B<print-pipe:> I<string>
752
753 Specify a command pipe for vt100 printer [default I<lpr(1)>]. Use
754 B<Print> to initiate a screen dump to the printer and B<Ctrl-Print> or
755 B<Shift-Print> to include the scrollback as well.
756
757 The string will be interpreted as if typed into the shell as-is.
758
759 Example:
760
761 URxvt*print-pipe: cat > $(TMPDIR=$HOME mktemp urxvt.XXXXXX)
762
763 This creates a new file in your home directory with the screen contents
764 everytime you hit C<Print>.
765
766 =item B<scrollBar:> I<boolean>
767
768 B<True>: enable the scrollbar [default]; option B<-sb>. B<False>:
769 disable the scrollbar; option B<+sb>.
770
771 =item B<scrollBar_right:> I<boolean>
772
773 B<True>: place the scrollbar on the right of the window; option B<-sr>.
774 B<False>: place the scrollbar on the left of the window; option B<+sr>.
775

777
778 B<True>: display an rxvt scrollbar without a trough; option B<-st>.
779 B<False>: display an rxvt scrollbar with a trough; option B<+st>.
780
781 =item B<scrollBar_align:> I<mode>
782
783 Align the B<top>, B<bottom> or B<centre> [default] of the scrollbar
784 thumb with the pointer on middle button press/drag.
785
786 =item B<scrollTtyOutput:> I<boolean>
787
788 B<True>: scroll to bottom when tty receives output; option B<-si>.
789 B<False>: do not scroll to bottom when tty receives output; option
790 B<+si>.
791
792 =item B<scrollWithBuffer:> I<boolean>
793
794 B<True>: scroll with scrollback buffer when tty receives new lines (and
795 B<scrollTtyOutput> is False); option B<-sw>. B<False>: do not scroll
796 with scrollback buffer when tty recieves new lines; option B<+sw>.
797
798 =item B<scrollTtyKeypress:> I<boolean>
799
800 B<True>: scroll to bottom when a non-special key is pressed. Special keys
801 are those which are intercepted by rxvt-unicode for special handling and
802 are not passed onto the shell; option B<-sk>. B<False>: do not scroll to
803 bottom when a non-special key is pressed; option B<+sk>.
804
805 =item B<saveLines:> I<number>
806
807 Save I<number> lines in the scrollback buffer [default 64]. This
808 resource is limited on most machines to 65535; option B<-sl>.

821
822 Set MWM hints to request a borderless window, i.e. if honoured by the
823 WM, the rxvt-unicode window will not have window decorations; option B<-bl>.
824
825 =item B<termName:> I<termname>
826
827 Specifies the terminal type name to be set in the B<TERM> environment
828 variable; option B<-tn>.
829
830 =item B<linespace:> I<number>
831
832 Specifies number of lines (pixel height) to insert between each row of
833 the display [default 0]; option B<-lsp>.
834
835 =item B<meta8:> I<boolean>
836
837 B<True>: handle Meta (Alt) + keypress to set the 8th bit. B<False>:
838 handle Meta (Alt) + keypress as an escape prefix [default].
839
840 =item B<mouseWheelScrollPage:> I<boolean>
841
842 B<True>: the mouse wheel scrolls a page full. B<False>: the mouse wheel
843 scrolls five lines [default].
844
845 =item B<pastableTabs:> I<boolean>
846
847 B<True>: store tabs as wide characters. B<False>: interpret tabs as cursor
848 movement only; option C<-ptab>.
849
850 =item B<cursorBlink:> I<boolean>
851
852 B<True>: blink the cursor. B<False>: do not blink the cursor [default];
853 option B<-bc>.
854
855 =item B<pointerBlank:> I<boolean>
856
857 B<True>: blank the pointer when a key is pressed or after a set number
858 of seconds of inactivity. B<False>: the pointer is always visible

862
863 Mouse pointer foreground colour.
864
865 =item B<pointerColor2:> I<colour>
866
867 Mouse pointer background colour.
868
869 =item B<pointerBlankDelay:> I<number>
870
871 Specifies number of seconds before blanking the pointer [default 2]. Use a
872 large number (e.g. C<987654321>) to effectively disable the timeout.
873
874 =item B<backspacekey:> I<string>
875
876 The string to send when the backspace key is pressed. If set to B<DEC>
877 or unset it will send B<Delete> (code 127) or, if shifted, B<Backspace>
878 (code 8) - which can be reversed with the appropriate DEC private mode
879 escape sequence.
880
881 =item B<deletekey:> I<string>
882
883 The string to send when the delete key (not the keypad delete key) is
884 pressed. If unset it will send the sequence traditionally associated
885 with the B<Execute> key.
886
887 =item B<cutchars:> I<string>
888
889 The characters used as delimiters for double-click word selection. The
890 built-in default:
891
892 B<< BACKSLASH `"'&()*,;<=>?@[]{|} >>

894 =item B<preeditType:> I<style>
895
896 B<OverTheSpot>, B<OffTheSpot>, B<Root>; option B<-pt>.
897
898 =item B<inputMethod:> I<name>
899
900 I<name> of inputMethod to use; option B<-im>.
901
902 =item B<imLocale:> I<name>
903
904 The locale to use for opening the IM. You can use an C<LC_CTYPE> of e.g.
905 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
906 input extension to be able to input japanese characters while staying in
907 another locale. option B<-imlocale>.
908
909 =item B<imFont:> I<fontset>
910
911 Specify the font-set used for XIM styles C<OverTheSpot> or
912 C<OffTheSpot>. It must be a standard X font set (XLFD patterns separated
913 by commas), i.e. it's not in the same format as the other font lists used
914 in @@RXVT_NAME@@. The default will be set-up to chose *any* suitable found
915 found, preferably one or two pixels differing in size to the base font.
916 option B<-imfont>.
917
918 =item B<tripleclickwords:> I<boolean>
919
920 Change the meaning of triple-click selection with the left mouse
921 button. Instead of selecting a full line it will extend the selection to
922 the end of the logical line only. option B<-tcw>.
923
924 =item B<insecure:> I<boolean>
925
926 Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
927 echo arbitrary strings like the icon name or the locale. This could be
928 abused if somebody gets 8-bit-clean access to your display, whether
929 through a mail client displaying mail bodies unfiltered or through
930 write(1) or any other means. Therefore, these sequences are disabled by
931 default. (Note that many other terminals, including xterm, have these
932 sequences enabled by default, which doesn't make it safer, though).
933
934 You can enable them by setting this boolean resource or specifying
935 B<-insecure> as an option. At the moment, this enables display-answer,
936 locale, findfont, icon label and window title requests as well as dynamic
937 menubar dispatch.
938
939 =item B<modifier:> I<modifier>
940
941 Set the key to be interpreted as the Meta key to: B<alt>, B<meta>,
942 B<hyper>, B<super>, B<mod1>, B<mod2>, B<mod3>, B<mod4>, B<mod5>; option
943 B<-mod>.
944
945 =item B<answerbackString:> I<string>
946
947 Specify the reply rxvt-unicode sends to the shell when an ENQ (control-E)
948 character is passed through. It may contain escape values as described
949 in the entry on B<keysym> following.
950
951 =item B<secondaryScreen:> I<bool>
952
953 Turn on/off secondary screen (default enabled).
954
955 =item B<secondaryScroll:> I<bool>
956
957 Turn on/off secondary screen scroll (default enabled). If the this
958 option is enabled, scrolls on the secondary screen will change the
959 scrollback buffer and switching to/from the secondary screen will
960 instead scroll the screen up.
961
962 =item B<hold>: I<bool>
963
964 Turn on/off hold window after exit support. If enabled, @@RXVT_NAME@@
965 will not immediately destroy its window when the program executed within
966 it exits. Instead, it will wait till it is being killed or closed by the
967 user.
968
969 =item B<keysym.>I<sym>: I<string>
970
971 Compile I<frills>: Associate I<string> with keysym I<sym>. The
972 intervening resource name B<keysym.> cannot be omitted.
973
974 The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
975 any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
976 B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
977 and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
978 B<2>, B<3>, B<4>, B<5>.
979
980 The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
981 whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
982 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
983 current application keymap mode state.
984
985 The spellings of I<key> can be obtained by using B<xev>(1) command or
986 searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
987 omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
988 keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
989 performed in an exact manner; however, the closest match is assured.
990
991 I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
992 C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
993 C<\000>: octal number) or verbatim control characters (C<^?>: delete,
994 C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
995 can start or end with whitespace.
996
997 Please note that you need to double the C<\> when using
998 C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
999 use C<\033> instead of C<\e> (and so on), which will work with both Xt and
1000 @@RXVT_NAME@@'s own processing).
1001
1002 You can define a range of keysyms in one shot by providing a I<string>
1003 with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
1004 should be a character not used by the strings.
1005
1006 Its usage can be demonstrated by an example:
1007
1008 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
1009
1010 The above line is equivalent to the following three lines:
1011
1012 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
1013 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
1014 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
1015
1016 If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1017 is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1018 example the following means "change the current locale to C<zh_CN.GBK>
1019 when Control-Meta-c is being pressed":
1020
1021 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1022
1023 Due the the large number of modifier combinations, a defined key mapping
1024 will match if at I<at least> the specified identifiers are being set, and
1025 no other key mappings with those and more bits are being defined. That
1026 means that defining a key map for C<a> will automatically provide
1027 definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1028 mappings themselves.
1029
1030 Unfortunately, this will override built-in key mappings. For example
1031 if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1032 C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1033 user-defined keymap using the C<builtin:> replacement:
1034
1035 URxvt.keysym.Insert: <my insert key sequence>
1036 URxvt.keysym.S-Insert: builtin:
1037
1038 The first line defines a mapping for C<Insert> and I<any> combination
1039 of modifiers. The second line re-establishes the default mapping for
1040 C<Shift-Insert>.
1041
1042 The following example will map Control-Meta-1 and Control-Meta-2 to
1043 the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1044 font-switching at runtime:

1057 =head1 THE SCROLLBAR
1058
1059 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
1060 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1061 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1062 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1063 arrows and its behaviour mimics that of I<xterm>
1064
1065 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
1066 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.
1067 Continuous scroll with B<Button2>.
1068
1069 =head1 MOUSE REPORTING
1070
1071 To temporarily override mouse reporting, for either the scrollbar or
1072 the normal text selection/insertion, hold either the Shift or the Meta
1073 (Alt) key while performing the desired mouse action.
1074
1075 If mouse reporting mode is active, the normal scrollbar actions are
1076 disabled -- on the assumption that we are using a fullscreen
1077 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1078 (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the
1079 up and down arrows sends B<ESC [ A> (Up) and B<ESC [ B> (Down),
1080 respectively.
1081
1082 =head1 TEXT SELECTION AND INSERTION
1083
1084 The behaviour of text selection and insertion mechanism is similar to
1085 I<xterm>(1).

1088
1089 =item B<Selection>:
1090
1091 Left click at the beginning of the region, drag to the end of the region
1092 and release; Right click to extend the marked region; Left double-click
1093 to select a word; Left triple-click to select the entire logical line
1094 (which can span multiple screen lines), unless modified by resource
1095 B<tripleclickwords>.
1096
1097 Starting a selection while pressing the B<Meta> key (or B<Meta+Ctrl> keys)
1098 (Compile: I<frills>) will create a rectangular selection instead of a
1099 normal one. In this mode, every selected row becomes its own line in the
1100 selection, and trailing whitespace is visually underlined and removed from
1101 the selection.
1102
1103 =item B<Insertion>:
1104
1105 Pressing and releasing the Middle mouse button (or B<Shift-Insert>) in
1106 an B<@@RXVT_NAME@@> window causes the current text selection to be
1107 inserted as if it had been typed on the keyboard.

1111 =head1 CHANGING FONTS
1112
1113 Changing fonts (or font sizes, respectively) via the keypad is not yet
1114 supported in rxvt-unicode. Bug me if you need this.
1115
1116 You can, however, switch fonts at runtime using escape sequences (and
1117 therefore using the menubar), e.g.:
1118
1119 printf '\e]710;%s\007' "9x15bold,xft:Kochi Gothic"
1120
1121 rxvt-unicode will automatically re-apply these fonts to the output so far.
1122
1123 =head1 ISO 14755 SUPPORT
1124
1125 ISO 14755 is a standard for entering and viewing unicode characters
1126 and character codes using the keyboard. It consists of 4 parts. The
1127 first part is available rxvt-unicode has been compiled with
1128 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1129 with C<--enable-iso14755>.
1130
1131 =over 4
1132
1133 =item * 5.1: Basic method
1134
1135 This allows you to enter unicode characters using their hexcode.
1136
1137 Start by pressing and holding both C<Control> and C<Shift>, then enter
1138 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1139 commit the character as if it were typed directly. While holding down
1140 C<Control> and C<Shift> you can also enter multiple characters by pressing
1141 C<Space>, which will commit the current character and lets you start a new
1142 one.
1143
1144 As an example of use, imagine a business card with a japanese e-mail
1145 address, which you cannot type. Fortunately, the card has the e-mail
1146 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1147 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1148 followed by releasing the modifier keys.
1149
1150 =item * 5.2: Keyboard symbols entry method
1151
1152 This mode lets you input characters representing the keycap symbols of
1153 your keyboard, if representable in the current locale encoding.
1154
1155 Start by pressing C<Control> and C<Shift> together, then releasing
1156 them. The next special key (cursor keys, home etc.) you enter will not
1157 invoke it's usual function but instead will insert the corresponding
1158 keycap symbol. The symbol will only be entered when the key has been
1159 released, otherwise pressing e.g. C<Shift> would enter the symbol for
1160 C<ISO Level 2 Switch>, although your intention might have been to enter a
1161 reverse tab (Shift-Tab).
1162
1163 =item * 5.3: Screen-selection entry method
1164
1165 While this is implemented already (it's basically the selection
1166 mechanism), it could be extended by displaying a unicode character map.
1167
1168 =item * 5.4: Feedback method for identifying displayed characters for later input
1169
1170 This method lets you display the unicode character code associated with
1171 characters already displayed.
1172
1173 You enter this mode by holding down C<Control> and C<Shift> together, then
1174 pressing and holding the left mouse button and moving around. The unicode
1175 hex code(s) (it might be a combining character) of the character under the
1176 pointer is displayed until you release C<Control> and C<Shift>.
1177
1178 In addition to the hex codes it will display the font used to draw this
1179 character - due to implementation reasons, characters combined with
1180 combining characters, line drawing characters and unknown characters will
1181 always be drawn using the built-in support font.

1185 With respect to conformance, rxvt-unicode is supposed to be compliant to
1186 both scenario A and B of ISO 14755, including part 5.2.

1196
1197 In addition to the default foreground and background colours,
1198 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1199 high-intensity bold/blink versions of the same). Here is a list of the
1200 colours with their B<rgb.txt> names.
1201

1209 B<color5> (magenta) = Magenta3
1210 B<color6> (cyan) = Cyan3
1211 B<color7> (white) = AntiqueWhite
1212 B<color8> (bright black) = Grey25
1213 B<color9> (bright red) = Red
1214 B<color10> (bright green) = Green
1215 B<color11> (bright yellow) = Yellow
1216 B<color12> (bright blue) = Blue
1217 B<color13> (bright magenta) = Magenta
1218 B<color14> (bright cyan) = Cyan
1219 B<color15> (bright white) = White
1220 B<foreground> = Black
1221 B<background> = White
1222
1223 =end table
1224
1225 It is also possible to specify the colour values of B<foreground>,
1226 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1227 a number 0-15, as a convenient shorthand to reference the colour name of
1228 color0-color15.
1229
1230 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1231 always swapping the foreground/background colours. This is in contrast to
1232 I<xterm>(1) where the colours are only swapped if they have not otherwise
1233 been specified. For example,
1234
1235 =over 4
1236
1237 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1238
1239 would yield White on Black, while on I<xterm>(1) it would yield Black
1240 on White.

1264 the colour code used as default foreground/text colour (or the string
1265 C<default> to indicate that the default-colour escape sequence is to be
1266 used), C<bg> is the colour code used as default background colour (or the
1267 string C<default>), and C<xpm> is the string C<default> if @@RXVT_NAME@@
1268 was compiled with XPM support. Libraries like C<ncurses> and C<slang> can
