139 .IX Header "DESCRIPTION"
140 \&\fBrxvt-unicode\fR, version \fB@@RXVT_VERSION@@\fR, is a colour vt102 terminal
141 emulator intended as an \fIxterm\fR(1) replacement for users who do not
142 require features such as Tektronix 4014 emulation and toolkit-style
143 configurability. As a result, \fBrxvt-unicode\fR uses much less swap space \*(--
144 a significant advantage on a machine serving many X sessions.
145 .SH "FREQUENTLY ASKED QUESTIONS"
146 .IX Header "FREQUENTLY ASKED QUESTIONS"
147 See @@RXVT_NAME@@(7) (try \f(CW\*(C`man 7 @@RXVT_NAME@@\*(C'\fR) for a list of
148 frequently asked questions and answer to them and some common
149 problems. That document is also accessible on the World-Wide-Web at
150 <http://cvs.schmorp.de/browse/rxvt\-unicode/doc/rxvt.7.html>.
151 .SH "RXVT-UNICODE VS. RXVT"
152 .IX Header "RXVT-UNICODE VS. RXVT"
153 Unlike the original rxvt, \fBrxvt-unicode\fR stores all text in Unicode
154 internally. That means it can store and display most scripts in the
155 world. Being a terminal emulator, however, some things are very difficult,
156 especially cursive scripts such as arabic, vertically written scripts
157 like mongolian or scripts requiring extremely complex combining rules,
158 like tibetan or devanagari. Don't expect pretty output when using these
159 scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
160 fine, though. A somewhat difficult case are right-to-left scripts, such
161 as hebrew: \fBrxvt-unicode\fR adopts the view that bidirectional algorithms
162 belong into the application, not the terminal emulator (too many things \*(--
163 such as cursor-movement while editing \*(-- break otherwise), but that might
164 change.
165 .PP
166 If you are looking for a terminal that supports more exotic scripts, let
167 me recommend \f(CW\*(C`mlterm\*(C'\fR, which is a very user friendly, lean and clean
168 terminal emulator. In fact, the reason rxvt-unicode was born was solely
169 because the author couldn't get \f(CW\*(C`mlterm\*(C'\fR to use one font for latin1 and
170 another for japanese.
171 .PP
172 Therefore another design rationale was the use of multiple fonts to
173 display characters: The idea of a single unicode font which many other
174 programs force onto its users never made sense to me: You should be able
175 to choose any font for any script freely.
176 .PP
177 Apart from that, rxvt-unicode is also much better internationalised than
178 its predecessor, supports things such as \s-1XFT\s0 and \s-1ISO\s0 14755 that are handy
179 in i18n\-environments, is faster, and has a lot bugs less than the original
180 rxvt. This all in addition to dozens of other small improvements.
181 .PP
182 It is still faithfully following the original rxvt idea of being lean
183 and nice on resources: for example, you can still configure rxvt-unicode
184 without most of its features to get a lean binary. It also comes with
185 a client/daemon pair that lets you open any number of terminal windows
186 from within a single process, which makes startup time very fast and
187 drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
188 @@RXVT_NAME@@c(1) (client).
189 .PP
190 It also makes technical information about escape sequences (which have
191 been extended) more accessible: see @@RXVT_NAME@@(7) for technical
192 reference documentation (escape sequences etc.).
193 .SH "OPTIONS"
194 .IX Header "OPTIONS"
195 The \fB@@RXVT_NAME@@\fR options (mostly a subset of \fIxterm\fR's) are listed
196 below. In keeping with the smaller-is-better philosophy, options may be
197 eliminated or default values chosen at compile\-time, so options and
198 defaults listed may not accurately reflect the version installed on
199 your system. `@@RXVT_NAME@@ \-h' gives a list of major compile-time options on
200 the \fIOptions\fR line. Option descriptions may be prefixed with which
201 compile option each is dependent upon. e.g. `Compile \fI\s-1XIM\s0\fR:' requires
202 \&\fI\s-1XIM\s0\fR on the \fIOptions\fR line. Note: `@@RXVT_NAME@@ \-help' gives a list of all
203 command-line options compiled into your version.
204 .PP
205 Note that \fB@@RXVT_NAME@@\fR permits the resource name to be used as a
206 long-option (\-\-/++ option) so the potential command-line options are
207 far greater than those listed. For example: `@@RXVT_NAME@@ \-\-loginShell \-\-color1
208 Orange'.

530 shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it

535 .Sp
536 It might be useful to know that @@RXVT_NAME@@ will not close file
537 descriptors passed to it (except for stdin/out/err, of course), so you

1116 If \fIstring\fR takes the form of \f(CW\*(C`command:STRING\*(C'\fR, the specified \fB\s-1STRING\s0\fR
1117 is interpreted and executed as @@RXVT_NAME@@'s control sequence. For

1125 If \fIstring\fR takes the form \f(CW\*(C`perl:STRING\*(C'\fR, then the specified \fB\s-1STRING\s0\fR
1126 is passed to the \f(CW\*(C`on_keyboard_command\*(C'\fR perl handler. See the @@RXVT_NAME@@\fIperl\fR\|(3)
1127 manpage. For example, the \fIselection\fR extension (activated via

1134 Due the the large number of modifier combinations, a defined key mapping
1135 will match if at \fIat least\fR the specified identifiers are being set, and
1136 no other key mappings with those and more bits are being defined. That
1137 means that defining a key map for \f(CW\*(C`a\*(C'\fR will automatically provide

1139 mappings themselves.
1140 .Sp
1141 Unfortunately, this will override built-in key mappings. For example
1142 if you overwrite the \f(CW\*(C`Insert\*(C'\fR key you will disable @@RXVT_NAME@@'s
1143 \&\f(CW\*(C`Shift\-Insert\*(C'\fR mapping. To re-enable that, you can poke \*(L"holes\*(R" into the
1144 user-defined keymap using the \f(CW\*(C`builtin:\*(C'\fR replacement:
1145 .Sp
1146 .Vb 2

1148 \& URxvt.keysym.S\-Insert: builtin:

1150 .Sp
1151 The first line defines a mapping for \f(CW\*(C`Insert\*(C'\fR and \fIany\fR combination
1152 of modifiers. The second line re-establishes the default mapping for
1153 \&\f(CW\*(C`Shift\-Insert\*(C'\fR.

1156 the fonts \f(CW\*(C`suxuseuro\*(C'\fR and \f(CW\*(C`9x15bold\*(C'\fR, so you can have some limited
