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.).

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'.

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.:

256 =item B<-ptab>|B<+ptab>
257
258 If enabled (default), "Horizontal Tab" characters are being stored as
259 actual wide characters in the screen buffer, which makes it possible to
260 select and paste them. Since a horizontal tab is a cursor movement and
261 not an actual glyph, this can sometimes be visually annoying as the cursor
262 on a tab character is displayed as a wide cursor; resource B<pastableTabs>.

301 =item B<-tn> I<termname>
302
303 This option specifies the name of the terminal type to be set in the
304 B<TERM> environment variable. This terminal type must exist in the
305 I<termcap(5)> database and should have I<li#> and I<co#> entries;
306 resource B<termName>.
307
308 =item B<-e> I<command [arguments]>
309
310 Run the command with its command-line arguments in the B<@@RXVT_NAME@@>
311 window; also sets the window title and icon name to be the basename of
312 the program being executed if neither I<-title> (I<-T>) nor I<-n> are
313 given on the command line. If this option is used, it must be the last
314 on the command-line. If there is no B<-e> option then the default is to
315 run the program specified by the B<SHELL> environment variable or,
316 failing that, I<sh(1)>.
317
318 =item B<-title> I<text>
319
320 Window title (B<-T> still respected); the default title is the basename
321 of the program specified after the B<-e> option, if any, otherwise the
322 application name; resource B<title>.
323
324 =item B<-n> I<text>
325

341 Compile I<XIM>: input method name. resource B<inputMethod>.
342
343 =item B<-imlocale> I<string>
344
345 The locale to use for opening the IM. You can use an C<LC_CTYPE> of e.g.
346 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
347 input extension to be able to input japanese characters while staying in
348 another locale. resource B<imLocale>.
349
350 =item B<-imfont> I<fontset>
351
352 Set the font set to use for the X Input Method, see resource B<imFont>
353 for more info.
354
355 =item B<-tcw>
356
357 Change the meaning of triple-click selection with the left mouse
358 button. Instead of selecting a full line it will extend the selection the
359 end of the logical line only. resource B<tripleclickwords>.
360
361 =item B<-insecure>
362
363 Enable "insecure" mode, which currently enables most of the escape
364 sequences that echo strings. See the resource B<insecure> for more
365 info.

381 B<secondaryScroll>.
382
383 =item B<-keysym.>I<sym> I<string>
384
385 Remap a key symbol. See resource B<keysym>.
386
387 =item B<-embed> I<windowid>
388
389 Tells @@RXVT_NAME@@ to embed it's windows into an already-existing window,
390 which enables applications to easily embed a terminal.
391
392 Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
393 shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
394 quite a bit, so don't expect it to keep some specific state. It's best to
395 create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
396
397 The window will not be destroyed when @@RXVT_NAME@@ exits.
398
399 It might be useful to know that @@RXVT_NAME@@ will not close file
400 descriptors passed to it (except for stdin/out/err, of course), so you
401 can use file descriptors to communicate with the programs within the
402 terminal. This works regardless of wether the C<-embed> option was used or
403 not.
404
405 Here is a short Gtk2-perl snippet that illustrates how this option can be
406 used (a longer example is in F<doc/embed>):
407
408 my $rxvt = new Gtk2::Socket;
409 $rxvt->signal_connect_after (realize => sub {
410 my $xid = $_[0]->window->get_xid;
411 system "@@RXVT_NAME@@ -embed $xid &";
412 });
413
414 =item B<-pty-fd> I<fileno>
415
416 Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
417 pair but instead use the given filehandle as the tty master. This is
418 useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
419 without having to run a program within it.
420
421 If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
422 entries and will not tinker with pty/tty permissions - you have to do that
423 yourself if you want that.
424
425 Here is a example in perl that illustrates how this option can be used (a
426 longer example is in F<doc/pty-fd>):
427
428 use IO::Pty;
429 use Fcntl;
430
431 my $pty = new IO::Pty;
432 fcntl $pty, F_SETFD, 0; # clear close-on-exec
433 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
434 close $pty;
435
436 # now communicate with rxvt
437 my $slave = $pty->slave;
438 while (<$slave>) { print $slave "got <$_>\n" }

441
442 =head1 RESOURCES (available also as long-options)
443
444 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
445 options) compiled into your version.
446
447 There are two different methods that @@RXVT_NAME@@ can use to get the
448 Xresource data: using the X libraries (Xrm*-functions) or internal
449 Xresources reader (B<~/.Xdefaults>). For the first method (ie.
450 B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
451 resources using X11 tools like B<xrdb>. Many distribution do also load
452 settings from the B<~/.Xresources> file when X starts. @@RXVT_NAME@@
453 will consult the following files/resources in order, with later settings
454 overwriting earlier ones:
455
456 1. system-wide app-defaults file, either locale-dependent OR global
457 2. app-defaults file in $XAPPLRESDIR
458 3. RESOURCE_MANAGER property on root-window OR $HOME/.Xdefaults
459 4. SCREEN_RESOURCES for the current screen
460 5. $XENVIRONMENT file OR $HOME/.Xdefaults-<nodename>
461
462 If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
463 lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
464 set in XAPPLOADDIR/URxvt (compile-time defined: usually
465 B</usr/lib/X11/app-defaults/URxvt>) and resources set in
466 B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
467 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
468 class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
469 resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
470 easily configured, while the class name B<URxvt> allows resources
471 unique to B<@@RXVT_NAME@@>, notably colours and key-handling, to be
472 shared between different B<@@RXVT_NAME@@> configurations. If no
473 resources are specified, suitable defaults will be used. Command-line
474 arguments can be used to override resource settings. The following
475 resources are allowed:
476
477 =over 4
478
479 =item B<geometry:> I<geom>
480
481 Create the window with the specified X window geometry [default 80x24];
482 option B<-geometry>.
483
484 =item B<background:> I<colour>
485
486 Use the specified colour as the window's background colour [default
487 White]; option B<-bg>.
488
489 =item B<foreground:> I<colour>
490
491 Use the specified colour as the window's foreground colour [default
492 Black]; option B<-fg>.
493
494 =item B<color>I<n>B<:> I<colour>
495
496 Use the specified colour for the colour value I<n>, where 0-7
497 corresponds to low-intensity (normal) colours and 8-15 corresponds to
498 high-intensity (bold = bright foreground, blink = bright background)
499 colours. The canonical names are as follows: 0=black, 1=red, 2=green,
500 3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
501 names used are listed in the B<COLORS AND GRAPHICS> section.
502
503 Colours higher than 15 cannot be set using resources (yet), but can be
504 changed using an escape command (see @@RXVT_NAME@@(7)).
505
506 Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
507 88 colour support). Colours 80-87 are evenly spaces grey steps.

510
511 =item B<colorIT:> I<colour>
512
513 Use the specified colour to display bold or italic characters when the

515 (Compile I<styles>) and this option is unset, reverse video is used instead.
516
517 =item B<colorUL:> I<colour>
518
519 Use the specified colour to display underlined characters when the
520 foreground colour is the default.
521

523
524 Use the specified colour as the background for reverse video
525 characters.
526
527 =item B<underlineColor:> I<colour>
528
529 If set, use the specified colour as the colour for the underline
530 itself. If unset, use the foreground colour.
531
532 =item B<cursorColor:> I<colour>
533
534 Use the specified colour for the cursor. The default is to use the
535 foreground colour; option B<-cr>.
536
537 =item B<cursorColor2:> I<colour>
538
539 Use the specified colour for the colour of the cursor text. For this to
540 take effect, B<cursorColor> must also be specified. The default is to
541 use the background colour.
542
543 =item B<reverseVideo:> I<boolean>
544
545 B<True>: simulate reverse video by foreground and background colours;
546 option B<-rv>. B<False>: regular screen colours [default]; option
547 B<+rv>. See note in B<COLORS AND GRAPHICS> section.
548
549 =item B<jumpScroll:> I<boolean>
550
551 B<True>: specify that jump scrolling should be used. When scrolling
552 quickly, fewer screen updates are performed [default]; option B<-j>.
553 B<False>: specify that smooth scrolling should be used; option B<+j>.
554
555 =item B<inheritPixmap:> I<boolean>
556
557 B<True>: make the background inherit the parent windows' pixmap, giving

559 pixmap.
560
561 =item B<fading:> I<number>
562
563 Fade the text by the given percentage when focus is lost; option B<-fade>.
564
565 =item B<fadeColor:> I<colour>
566
567 Fade to this colour, when fading is used (see B<fading:>). The default
568 colour is black; option B<-fadecolor>.
569
570 =item B<tintColor:> I<colour>
571
572 Tint the transparent background pixmap with the given colour; option
573 B<-tint>.
574
575 =item B<shading:> I<number>

582 Use the specified colour for the scrollbar [default #B2B2B2].
583
584 =item B<troughColor:> I<colour>
585
586 Use the specified colour for the scrollbar's trough area [default
587 #969696]. Only relevant for rxvt (non XTerm/NeXT) scrollbar.
588
589 =item B<borderColor:> I<colour>
590
591 The colour of the border around the text area and between the scrollbar
592 and the text.
593
594 =item B<backgroundPixmap:> I<file[;geom]>
595
596 Use the specified XPM file (note the `.xpm' extension is optional) for
597 the background and also optionally specify its scaling with a geometry
598 string B<WxH+X+Y>, in which B<"W" / "H"> specify the
599 horizontal/vertical scale (percent) and B<"X" / "Y"> locate the image
600 centre (percent). A scale of 0 displays the image with tiling. A scale
601 of 1 displays the image without any scaling. A scale of 2 to 9
602 specifies an integer number of images in that direction. No image will
603 be magnified beyond 10 times its original size. The maximum permitted
604 scale is 1000. [default 0x0+50+50]
605
606 =item B<menu:> I<file[;tag]>
607
608 Read in the specified menu file (note the `.menu' extension is
609 optional) and also optionally specify a starting tag to find. See the
610 reference documentation for details on the syntax for the menuBar.
611
612 =item B<path:> I<path>
613
614 Specify the colon-delimited search path for finding files (XPM and
615 menus), in addition to the paths specified by the B<RXVTPATH> and
616 B<PATH> environment variables.
617
618 =item B<font:> I<fontlist>
619
620 Select the fonts to be used. This is a comma separated list of font
621 names that are used in turn when trying to display Unicode characters.
622 The first font defines the cell size for characters; other fonts might
623 be smaller, but not larger. A reasonable default font list is always
624 appended to it. option B<-fn>.
625
626 Each font can either be a standard X11 core font (XLFD) name, with
627 optional prefix C<x:> or a Xft font (Compile I<xft>), prefixed with C<xft:>.
628
629 In addition, each font can be prefixed with additional hints and
630 specifications enclosed in square brackets (C<[]>). The only available
631 hint currently is C<codeset=codeset-name>, and this is only used for Xft
632 fonts.
633
634 For example, this font resource
635
636 URxvt*font: 9x15bold,\
637 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
638 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
639 [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
640 xft:Code2000:antialias=false
641
642 specifies five fonts to be used. The first one is C<9x15bold> (actually
643 the iso8859-1 version of the second font), which is the base font (because
644 it is named first) and thus defines the character cell grid to be 9 pixels
645 wide and 15 pixels high.
646
647 The second font is just used to add additional unicode characters not in
648 the base font, likewise the third, which is unfortunately non-bold, but
649 the bold version of the font does contain less characters, so this is a
650 useful supplement.
651
652 The third font is an Xft font with aliasing turned off, and the characters
653 are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
654 contains other characters, but we are not interested in them.
655
656 The last font is a useful catch-all font that supplies most of the
657 remaining unicode characters.
658
659 =item B<boldFont:> I<fontlist>
660
661 =item B<italicFont:> I<fontlist>
662
663 =item B<boldItalicFont:> I<fontlist>
664
665 The font list to use for displaying B<bold>, I<italic> or B<< I<bold
666 italic> >> characters, respectively.
667
668 If specified and non-empty, then the syntax is the same as for the
669 B<font>-resource, and the given font list will be used as is, which makes
670 it possible to substitute completely different font styles for bold and
671 italic.
672
673 If unset (the default), a suitable font list will be synthesized by
674 "morphing" the normal text font list into the desired shape. If that is
675 not possible, replacement fonts of the desired shape will be tried.
676
677 If set, but empty, then this specific style is disabled and the normal
678 text font will being used for the given style.
679
680 =item B<selectstyle:> I<mode>
681
682 Set mouse selection style to B<old> which is 2.20, B<oldword> which is

685
686 =item B<scrollstyle:> I<mode>
687
688 Set scrollbar style to B<rxvt>, B<plain>, B<next> or B<xterm>. B<plain> is
689 the author's favourite.
690
691 =item B<title:> I<string>
692
693 Set window title string, the default title is the command-line
694 specified after the B<-e> option, if any, otherwise the application
695 name; option B<-title>.
696
697 =item B<iconName:> I<string>
698
699 Set the name used to label the window's icon or displayed in an icon
700 manager window, it also sets the window's title unless it is explicitly
701 set; option B<-n>.
702
703 =item B<mapAlert:> I<boolean>
704
705 B<True>: de-iconify (map) on receipt of a bell character. B<False>: no

719 =item B<utmpInhibit:> I<boolean>
720
721 B<True>: inhibit writing record into the system log file B<utmp>;
722 option B<-ut>. B<False>: write record into the system log file B<utmp>
723 [default]; option B<+ut>.
724
725 =item B<print-pipe:> I<string>
726
727 Specify a command pipe for vt100 printer [default I<lpr(1)>]. Use
728 B<Print> to initiate a screen dump to the printer and B<Ctrl-Print> or
729 B<Shift-Print> to include the scrollback as well.
730
731 The string will be interpreted as if typed into the shell as-is.
732
733 Example:
734
735 URxvt*print-pipe: cat > $(TMPDIR=$HOME mktemp urxvt.XXXXXX)
736
737 This creates a new file in your home directory with the screen contents
738 everytime you hit C<Print>.
739
740 =item B<scrollBar:> I<boolean>
741
742 B<True>: enable the scrollbar [default]; option B<-sb>. B<False>:

751
752 B<True>: display an rxvt scrollbar without a trough; option B<-st>.
753 B<False>: display an rxvt scrollbar with a trough; option B<+st>.
754

756
757 Align the B<top>, B<bottom> or B<centre> [default] of the scrollbar
758 thumb with the pointer on middle button press/drag.
759
760 =item B<scrollTtyOutput:> I<boolean>
761
762 B<True>: scroll to bottom when tty receives output; option B<-si>.
763 B<False>: do not scroll to bottom when tty receives output; option
764 B<+si>.
765
766 =item B<scrollWithBuffer:> I<boolean>
767
768 B<True>: scroll with scrollback buffer when tty receives new lines (and
769 B<scrollTtyOutput> is False); option B<-sw>. B<False>: do not scroll
770 with scrollback buffer when tty recieves new lines; option B<+sw>.
771
772 =item B<scrollTtyKeypress:> I<boolean>
773
774 B<True>: scroll to bottom when a non-special key is pressed. Special keys
775 are those which are intercepted by rxvt-unicode for special handling and
776 are not passed onto the shell; option B<-sk>. B<False>: do not scroll to
777 bottom when a non-special key is pressed; option B<+sk>.
778
779 =item B<saveLines:> I<number>
780
781 Save I<number> lines in the scrollback buffer [default 64]. This
782 resource is limited on most machines to 65535; option B<-sl>.

807 the display [default 0]; option B<-lsp>.
808
809 =item B<meta8:> I<boolean>
810
811 B<True>: handle Meta (Alt) + keypress to set the 8th bit. B<False>:
812 handle Meta (Alt) + keypress as an escape prefix [default].
813
814 =item B<mouseWheelScrollPage:> I<boolean>
815
816 B<True>: the mouse wheel scrolls a page full. B<False>: the mouse wheel
817 scrolls five lines [default].
818
819 =item B<pastableTabs:> I<boolean>

840
841 Mouse pointer background colour.
842
843 =item B<pointerBlankDelay:> I<number>
844
845 Specifies number of seconds before blanking the pointer [default 2]. Use a
846 large number (e.g. C<987654321>) to effectively disable the timeout.
847
848 =item B<backspacekey:> I<string>
849
850 The string to send when the backspace key is pressed. If set to B<DEC>
851 or unset it will send B<Delete> (code 127) or, if shifted, B<Backspace>
852 (code 8) - which can be reversed with the appropriate DEC private mode
853 escape sequence.
854
855 =item B<deletekey:> I<string>
856
857 The string to send when the delete key (not the keypad delete key) is
858 pressed. If unset it will send the sequence traditionally associated
859 with the B<Execute> key.
860
861 =item B<cutchars:> I<string>
862
863 The characters used as delimiters for double-click word selection. The
864 built-in default:
865
866 B<< BACKSLASH `"'&()*,;<=>?@[]{|} >>

869
870 B<OverTheSpot>, B<OffTheSpot>, B<Root>; option B<-pt>.
871
872 =item B<inputMethod:> I<name>
873
874 I<name> of inputMethod to use; option B<-im>.
875
876 =item B<imLocale:> I<name>
877
878 The locale to use for opening the IM. You can use an C<LC_CTYPE> of e.g.
879 C<de_DE.UTF-8> for normal text processing but C<ja_JP.EUC-JP> for the
880 input extension to be able to input japanese characters while staying in
881 another locale. option B<-imlocale>.
882
883 =item B<imFont:> I<fontset>
884
885 Specify the font-set used for XIM styles C<OverTheSpot> or
886 C<OffTheSpot>. It must be a standard X font set (XLFD patterns separated
887 by commas), i.e. it's not in the same format as the other font lists used
888 in @@RXVT_NAME@@. The default will be set-up to chose *any* suitable found
889 found, preferably one or two pixels differing in size to the base font.
890 option B<-imfont>.
891
892 =item B<tripleclickwords:> I<boolean>
893
894 Change the meaning of triple-click selection with the left mouse
895 button. Instead of selecting a full line it will extend the selection to
896 the end of the logical line only. option B<-tcw>.
897
898 =item B<insecure:> I<boolean>
899
900 Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
901 echo arbitrary strings like the icon name or the locale. This could be
902 abused if somebody gets 8-bit-clean access to your display, whether
903 throuh a mail client displaying mail bodies unfiltered or though
904 write(1). Therefore, these sequences are disabled by default. (Note
905 that other terminals, including xterm, have these sequences
906 enabled by default). You can enable them by setting this boolean
907 resource or specifying B<-insecure> as an option. At the moment, this
908 enabled display-answer, locale, findfont, icon label and window title
909 requests as well as dynamic menubar dispatch.
910
911 =item B<modifier:> I<modifier>
912
913 Set the key to be interpreted as the Meta key to: B<alt>, B<meta>,
914 B<hyper>, B<super>, B<mod1>, B<mod2>, B<mod3>, B<mod4>, B<mod5>; option
915 B<-mod>.
916
917 =item B<answerbackString:> I<string>
918
919 Specify the reply rxvt-unicode sends to the shell when an ENQ (control-E)
920 character is passed through. It may contain escape values as described
921 in the entry on B<keysym> following.
922
923 =item B<secondaryScreen:> I<bool>
924
925 Turn on/off secondary screen (default enabled).
926
927 =item B<secondaryScroll:> I<bool>
928
929 Turn on/off secondary screen scroll (default enabled). If the this
930 option is enabled, scrolls on the secondary screen will change the
931 scrollback buffer and switching to/from the secondary screen will
932 instead scroll the screen up.
933
934 =item B<keysym.>I<sym>: I<string>
935
936 Compile I<frills>: Associate I<string> with keysym I<sym>. The
937 intervening resource name B<keysym.> cannot be omitted.
938
939 The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
940 any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
941 B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
942 and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
943 B<2>, B<3>, B<4>, B<5>.
944
945 The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
946 whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
947 keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
948 current application keymap mode state.
949
950 The spellings of I<key> can be obtained by using B<xev>(1) command or
951 searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
952 omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
953 keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
954 performed in an exact manner; however, the closest match is assured.
955
956 I<string> may contain escape values (C<\a>: bell, C<\b>: backspace,
957 C<\e>, C<\E>: escape, C<\n>: newline, C<\r>: carriage return, C<\t>: tab,
958 C<\000>: octal number) or verbatim control characters (C<^?>: delete,
959 C<^@>: null, C<^A> ...) and may be enclosed with double quotes so that it
960 can start or end with whitespace.
961
962 Please note that you need to double the C<\> when using
963 C<--enable-xgetdefault>, as X itself does it's own de-escaping (you can
964 use C<\033> instead of C<\e> (and so on), which will work with both Xt and
965 @@RXVT_NAME@@'s own processing).
966
967 You can define a range of keysyms in one shot by providing a I<string>
968 with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimeter `/'
969 should be a character not used by the strings.
970
971 Its usage can be demonstrated by an example:
972
973 URxvt.keysym.M-C-0x61: list|\033<M-C-|abc|>
974
975 The above line is equivalent to the following three lines:
976
977 URxvt.keysym.Meta-Control-0x61: \033<M-C-a>
978 URxvt.keysym.Meta-Control-0x62: \033<M-C-b>
979 URxvt.keysym.Meta-Control-0x63: \033<M-C-c>
980
981 If I<string> takes the form of C<command:STRING>, the specified B<STRING>
982 is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
983 example the following means "change the current locale to C<zh_CN.GBK>
984 when Control-Meta-c is being pressed":
985
986 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
987
988 Due the the large number of modifier combinations, a defined key mapping
989 will match if at I<at least> the specified identifiers are being set, and
990 no other key mappings with those and more bits are being defined. That
991 means that defining a key map for C<a> will automatically provide
992 definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
993 mappings themselves.
994
995 Unfortunately, this will override built-in key mappings. For example
996 if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
997 C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
998 user-defined keymap using the C<builtin:> replacement:
999
1000 URxvt.keysym.Insert: <my insert key sequence>
1001 URxvt.keysym.S-Insert: builtin:
1002
1003 The first line defines a mapping for C<Insert> and I<any> combination
1004 of modifiers. The second line re-establishes the default mapping for
1005 C<Shift-Insert>.
1006
1007 The following example will map Control-Meta-1 and Control-Meta-2 to
1008 the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1009 font-switching at runtime:
1010
1011 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1012 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1013
1014 Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1015 info):
1016
1017 URxvt.keysym.M-C-3: command:\033[8;25;80t
1018 URxvt.keysym.M-C-4: command:\033[8;48;110t
1019
1020 =back
1021
1022 =head1 THE SCROLLBAR
1023
1024 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
1025 (resource: B<saveLines>) and can be scrolled back using the scrollbar
1026 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
1027 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
1028 arrows and its behaviour mimics that of I<xterm>
1029
1030 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
1031 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.
1032 Continuous scroll with B<Button2>.
1033
1034 =head1 MOUSE REPORTING
1035
1036 To temporarily override mouse reporting, for either the scrollbar or
1037 the normal text selection/insertion, hold either the Shift or the Meta
1038 (Alt) key while performing the desired mouse action.
1039
1040 If mouse reporting mode is active, the normal scrollbar actions are
1041 disabled -- on the assumption that we are using a fullscreen
1042 application. Instead, pressing Button1 and Button3 sends B<ESC [ 6 ~>
1043 (Next) and B<ESC [ 5 ~> (Prior), respectively. Similarly, clicking on the
1044 up and down arrows sends B<ESC [ A> (Up) and B<ESC [ B> (Down),
1045 respectively.

1054 =item B<Selection>:
1055
1056 Left click at the beginning of the region, drag to the end of the region
1057 and release; Right click to extend the marked region; Left double-click
1058 to select a word; Left triple-click to select the entire logical line
1059 (which can span multiple screen lines), unless modified by resource
1060 B<tripleclickwords>.
1061
1062 Starting a selection while pressing the B<Meta> key (or B<Meta+Ctrl> keys)
1063 (Compile: I<frills>) will create a rectangular selection instead of a normal
1064 one.
1065
1066 =item B<Insertion>:
1067
1068 Pressing and releasing the Middle mouse button (or B<Shift-Insert>) in
1069 an B<@@RXVT_NAME@@> window causes the current text selection to be
1070 inserted as if it had been typed on the keyboard.

1074 =head1 CHANGING FONTS
1075
1076 Changing fonts (or font sizes, respectively) via the keypad is not yet
1077 supported in rxvt-unicode. Bug me if you need this.
1078
1079 You can, however, switch fonts at runtime using escape sequences (and
1080 therefore using the menubar), e.g.:
1081
1082 printf '\e]701;%s\007' "9x15bold,xft:Kochi Gothic"
1083
1084 rxvt-unicode will automatically re-apply these fonts to the output so far.
1085
1086 =head1 ISO 14755 SUPPORT
1087
1088 ISO 14755 is a standard for entering and viewing unicode characters
1089 and character codes using the keyboard. It consists of 4 parts. The
1090 first part is available rxvt-unicode has been compiled with
1091 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
1092 with C<--enable-iso14755>.
1093
1094 =over 4
1095
1096 =item * 5.1: Basic method
1097
1098 This allows you to enter unicode characters using their hexcode.
1099
1100 Start by pressing and holding both C<Control> and C<Shift>, then enter
1101 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
1102 commit the character as if it were typed directly. While holding down
1103 C<Control> and C<Shift> you can also enter multiple characters by pressing
1104 C<Space>, which will commit the current character and lets you start a new
1105 one.
1106
1107 As an example of use, imagine a business card with a japanese e-mail
1108 address, which you cannot type. Fortunately, the card has the e-mail
1109 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
1110 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
1111 followed by releasing the modifier keys.
1112
1113 =item * 5.2: Keyboard symbols entry method
1114
1115 This mode lets you input characters representing the keycap symbols of
1116 your keyboard, if representable in the current locale encoding.
1117
1118 Start by pressing C<Control> and C<Shift> together, then releasing
1119 them. The next special key (cursor keys, home etc.) you enter will not
1120 invoke it's usual function but instead will insert the corresponding
1121 keycap symbol. The symbol will only be entered when the key has been
1122 released, otherwise pressing e.g. C<Shift> would enter the symbol for
1123 C<ISO Level 2 Switch>, although your intention might have been to enter a
1124 reverse tab (Shift-Tab).
1125
1126 =item * 5.3: Screen-selection entry method
1127
1128 While this is implemented already (it's basically the selection
1129 mechanism), it could be extended by displaying a unicode character map.
1130
1131 =item * 5.4: Feedback method for identifying displayed characters for later input
1132
1133 This method lets you display the unicode character code associated with
1134 characters already displayed.
1135
1136 You enter this mode by holding down C<Control> and C<Shift> together, then
1137 pressing and holding the left mouse button and moving around. The unicode
1138 hex code(s) (it might be a combining character) of the character under the
1139 pointer is displayed until you release C<Control> and C<Shift>.
1140
1141 In addition to the hex codes it will display the font used to draw this
1142 character - due to implementation reasons, characters combined with
1143 combining characters, line drawing characters and unknown characters will
1144 always be drawn using the built-in support font.

1148 With respect to conformance, rxvt-unicode is supposed to be compliant to
1149 both scenario A and B of ISO 14755, including part 5.2.

1158 =head1 COLORS AND GRAPHICS
1159
1160 In addition to the default foreground and background colours,
1161 B<@@RXVT_NAME@@> can display up to 16 colours (8 ANSI colours plus
1162 high-intensity bold/blink versions of the same). Here is a list of the
1163 colours with their B<rgb.txt> names.
1164
1165 =begin table

1171 B<color4> (blue) = Blue3
1172 B<color5> (magenta) = Magenta3
1173 B<color6> (cyan) = Cyan3
1174 B<color7> (white) = AntiqueWhite
1175 B<color8> (bright black) = Grey25
1176 B<color9> (bright red) = Red
1177 B<color10> (bright green) = Green
1178 B<color11> (bright yellow) = Yellow
1179 B<color12> (bright blue) = Blue
1180 B<color13> (bright magenta) = Magenta
1181 B<color14> (bright cyan) = Cyan
1182 B<color15> (bright white) = White
1183 B<foreground> = Black
1184 B<background> = White
1185
1186 =end table
1187
1188 It is also possible to specify the colour values of B<foreground>,
1189 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
1190 a number 0-15, as a convenient shorthand to reference the colour name of
1191 color0-color15.
1192
1193 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
1194 always swapping the foreground/background colours. This is in contrast to
1195 I<xterm>(1) where the colours are only swapped if they have not otherwise
1196 been specified. For example,
1197
1198 =over 4
1199
1200 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>
1201
1202 would yield White on Black, while on I<xterm>(1) it would yield Black
1203 on White.

1227 the colour code used as default foreground/text colour (or the string
1228 C<default> to indicate that the default-colour escape sequence is to be
1229 used), C<bg> is the colour code used as default background colour (or the
1230 string C<default>), and C<xpm> is the string C<default> if @@RXVT_NAME@@
1231 was compiled with XPM support. Libraries like C<ncurses> and C<slang> can
1232 (and do) use this information to optimize screen output.
