		172	Beginning with version 7.3, there is a perl extension that implements a
		173	simple tabbed terminal. It is installed by default, so any of these should
		174	give you tabs:

177	This will keep the default extensions, but disable the two popup
178	extensions. Some extensions can also be configured, for example,
179	scrollback search mode is triggered by \fBM\-s\fR. You can move it to any
180	other combination either by setting the \fBsearchable-scrollback\fR resource:

		183	.PP
		184	It will also work fine with tabbing functionality of many window managers
		185	or similar tabbing programs, and its embedding-features allow it to be
		186	embedded into other programs, as witnessed by \fIdoc/rxvt\-tabbed\fR or
		187	the upcoming \f(CW\*(C`Gtk2::URxvt\*(C'\fR perl module, which features a tabbed urxvt
		188	(murxvt) terminal as an example embedding application.

		190	\fIHow do I know which rxvt-unicode version I'm using?\fR
		191	.IX Subsection "How do I know which rxvt-unicode version I'm using?"
		192	.PP
		193	The version number is displayed with the usage (\-h). Also the escape
		194	sequence \f(CW\*(C`ESC [ 8 n\*(C'\fR sets the window title to the version number. When
		195	using the @@URXVT_NAME@@c client, the version displayed is that of the
		196	daemon.
		197	.PP
		198	\fIRxvt-unicode uses gobs of memory, how can I reduce that?\fR
		199	.IX Subsection "Rxvt-unicode uses gobs of memory, how can I reduce that?"
		200	.PP
		201	Rxvt-unicode tries to obey the rule of not charging you for something you
		202	don't use. One thing you should try is to configure out all settings that
		203	you don't need, for example, Xft support is a resource hog by design,
		204	when used. Compiling it out ensures that no Xft font will be loaded
		205	accidentally when rxvt-unicode tries to find a font for your characters.
		206	.PP
		207	Also, many people (me included) like large windows and even larger
		208	scrollback buffers: Without \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR, rxvt-unicode will use
		209	6 bytes per screen cell. For a 160x?? window this amounts to almost a
		210	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		211	use 10 Megabytes of memory. With \f(CW\*(C`\-\-enable\-unicode3\*(C'\fR it gets worse, as
		212	rxvt-unicode then uses 8 bytes per screen cell.
		213	.PP
		214	\fIHow can I start @@URXVT_NAME@@d in a race-free way?\fR

		217	Try \f(CW\*(C`@@URXVT_NAME@@d \-f \-o\*(C'\fR, which tells @@URXVT_NAME@@d to open the

		221	.IX Subsection "How do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc."
		222	.PP
		223	The original rxvt and rxvt-unicode always export the variable \*(L"\s-1COLORTERM\s0\*(R",
		224	so you can check and see if that is set. Note that several programs, \s-1JED\s0,
		225	slrn, Midnight Commander automatically check this variable to decide
		226	whether or not to use color.
		227	.PP
		228	\fIHow do I set the correct, full \s-1IP\s0 address for the \s-1DISPLAY\s0 variable?\fR
		229	.IX Subsection "How do I set the correct, full IP address for the DISPLAY variable?"
		230	.PP
		231	If you've compiled rxvt-unicode with \s-1DISPLAY_IS_IP\s0 and have enabled
		232	insecure mode then it is possible to use the following shell script
		233	snippets to correctly set the display. If your version of rxvt-unicode
		234	wasn't also compiled with \s-1ESCZ_ANSWER\s0 (as assumed in these snippets) then
		235	the \s-1COLORTERM\s0 variable can be used to distinguish rxvt-unicode from a
		236	regular xterm.

		754	.PP
		755	Rxvt-unicode tries to inherit the current stty settings and uses the value
		756	of `erase' to guess the value for backspace. If rxvt-unicode wasn't

		758	system value of `erase', which corresponds to \s-1CERASE\s0 in <termios.h>, will

672	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
673	specific \*(L"utf\-8\*(R" mode, such as xterm. In fact, it doesn't even know about
674	\&\s-1UTF\-8\s0 or any other encodings with respect to terminal I/O.
675	.Sp
676	The reasons is that there exists a perfectly fine mechanism for selecting
677	the encoding, doing I/O and (most important) communicating this to all
678	applications so everybody agrees on character properties such as width
679	and code number. This mechanism is the \fIlocale\fR. Applications not using
680	that info will have problems (for example, \f(CW\*(C`xterm\*(C'\fR gets the width of
681	characters wrong as it uses it's own, locale-independent table under all
682	locales).
683	.Sp
684	Rxvt-unicode uses the \f(CW\*(C`LC_CTYPE\*(C'\fR locale category to select encoding. All
685	programs doing the same (that is, most) will automatically agree in the
686	interpretation of characters.
687	.Sp
688	Unfortunately, there is no system-independent way to select locales, nor
689	is there a standard on how locale specifiers will look like.
690	.Sp
691	On most systems, the content of the \f(CW\*(C`LC_CTYPE\*(C'\fR environment variable
692	contains an arbitrary string which corresponds to an already-installed
693	locale. Common names for locales are \f(CW\*(C`en_US.UTF\-8\*(C'\fR, \f(CW\*(C`de_DE.ISO\-8859\-15\*(C'\fR,
694	\&\f(CW\*(C`ja_JP.EUC\-JP\*(C'\fR, i.e. \f(CW\*(C`language_country.encoding\*(C'\fR, but other forms
695	(i.e. \f(CW\*(C`de\*(C'\fR or \f(CW\*(C`german\*(C'\fR) are also common.
696	.Sp
697	Rxvt-unicode ignores all other locale categories, and except for
698	the encoding, ignores country or language-specific settings,
699	i.e. \f(CW\*(C`de_DE.UTF\-8\*(C'\fR and \f(CW\*(C`ja_JP.UTF\-8\*(C'\fR are the normally same to

717	(e.g. \s-1UTF\-8\s0). For example, I use this script to start \f(CW\*(C`xjdic\*(C'\fR, which
