165=item readline (enabled by default)
166
167A support package that tries to make editing with readline easier. At
168the moment, it reacts to clicking shift-left mouse button by trying to
169move the text cursor to this position. It does so by generating as many
170cursor-left or cursor-right keypresses as required (the this only works
171for programs that correctly support wide characters).
172
173To avoid too many false positives, this is only done when:
174
175=over 4
176
177=item - the tty is in ICANON state.
178
179=item - the text cursor is visible.
180
181=item - the primary screen is currently being displayed.
182
183=item - the mouse is on the same (multi-row-) line as the text cursor.

144=item mark-urls 225=item tabbed
145 226
227This transforms the terminal into a tabbar with additional terminals, that
228is, it implements what is commonly referred to as "tabbed terminal". The topmost line
229displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
230button per tab.
231
232Clicking a button will activate that tab. Pressing B<Shift-Left> and
233B<Shift-Right> will switch to the tab left or right of the current one,
234while B<Shift-Down> creates a new tab.
235
236The tabbar itself can be configured similarly to a normal terminal, but
237with a resource class of C<URxvt.tabbed>. In addition, it supports the
238following four resources (shown with defaults):
239
240 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
241 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
242 URxvt.tabbed.tab-fg: <colour-index, default 0>
243 URxvt.tabbed.tab-bg: <colour-index, default 1>

246indices.

254(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
255with the matched text as first argument. The default configuration is
256suitable for matching URLs and launching a web browser, like the
257former "mark-urls" extension.
258
259The default pattern to match URLs can be overridden with the
260C<matcher.pattern.0> resource, and additional patterns can be specified
261with numbered patterns, in a manner similar to the "selection" extension.
262The launcher can also be overridden on a per-pattern basis.
263
264Example configuration:
265
266 URxvt.perl-ext: default,matcher

274=item xim-onthespot
275
276This (experimental) perl extension implements OnTheSpot editing. It does
277not work perfectly, and some input methods don't seem to work well with
278OnTheSpot editing in general, but it seems to work at leats for SCIM and
279kinput2.
280
281You enable it by specifying this extension and a preedit style of

286=item kuake<hotkey>
287
288A very primitive quake-console-like extension. It was inspired by a
289description of how the programs C<kuake> and C<yakuake> work: Whenever the
290user presses a global accelerator key (by default C<F10>), the terminal
291will show or hide itself. Another press of the accelerator key will hide
292or show it again.
293
294Initially, the window will not be shown when using this extension.
295
296This is useful if you need a single terminal thats not using any desktop
297space most of the time but is quickly available at the press of a key.
298
299The accelerator key is grabbed regardless of any modifiers, so this
300extension will actually grab a physical key just for this function.
301
302If you want a quake-like animation, tell your window manager to do so
303(fvwm can do it).
304
305=item automove-background
306
307This is basically a very small extension that dynamically changes the
308background pixmap offset to the window position, in effect creating the
309same effect as pseudo transparency with a custom pixmap. No scaling is
310supported in this mode. Example:

333
334We use it to implement a "distributed selection mechanism", which just
335means that one command uploads the file to a remote server, and another
336reads it.
337
338The commands can be set using the C<URxvt.remote-selection.store> and
339C<URxvt.remote-selection.fetch> resources. The first should read the
340selection to store from STDIN (always in UTF-8), the second should provide
341the selection data on STDOUT (also in UTF-8).
342
343The defaults (which are likely useless to you) use rsh and cat:
