162=item readline (enabled by default)
163
164A support package that tries to make editing with readline easier. At
165the moment, it reacts to clicking shift-left mouse button by trying to
166move the text cursor to this position. It does so by generating as many
167cursor-left or cursor-right keypresses as required (the this only works
168for programs that correctly support wide characters).
169
170To avoid too many false positives, this is only done when:
171
172=over 4
173
174=item - the tty is in ICANON state.
175
176=item - the text cursor is visible.
177
178=item - the primary screen is currently being displayed.
179
180=item - the mouse is on the same (multi-row-) line as the text cursor.

185might interfere with selection creation in harmless ways.

167=item mark-urls 222=item tabbed
168 223
224This transforms the terminal into a tabbar with additional terminals, that
225is, it implements what is commonly referred to as "tabbed terminal". The topmost line
226displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
227button per tab.
228
229Clicking a button will activate that tab. Pressing B<Shift-Left> and
230B<Shift-Right> will switch to the tab left or right of the current one,
231while B<Shift-Down> creates a new tab.
232
233The tabbar itself can be configured similarly to a normal terminal, but
234with a resource class of C<URxvt.tabbed>. In addition, it supports the
235following four resources (shown with defaults):
236
237 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
238 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
239 URxvt.tabbed.tab-fg: <colour-index, default 0>
240 URxvt.tabbed.tab-bg: <colour-index, default 1>

251(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
252with the matched text as first argument. The default configuration is
253suitable for matching URLs and launching a web browser, like the
254former "mark-urls" extension.
255
256The default pattern to match URLs can be overridden with the
257C<matcher.pattern.0> resource, and additional patterns can be specified
258with numbered patterns, in a manner similar to the "selection" extension.
259The launcher can also be overridden on a per-pattern basis.
260
261Example configuration:

270=item xim-onthespot
271
272This (experimental) perl extension implements OnTheSpot editing. It does
273not work perfectly, and some input methods don't seem to work well with
274OnTheSpot editing in general, but it seems to work at leats for SCIM and
275kinput2.

282=item kuake<hotkey>
283
284A very primitive quake-console-like extension. It was inspired by a
285description of how the programs C<kuake> and C<yakuake> work: Whenever the
286user presses a global accelerator key (by default C<F10>), the terminal
287will show or hide itself. Another press of the accelerator key will hide
288or show it again.
289
290Initially, the window will not be shown when using this extension.
291
292This is useful if you need a single terminal thats not using any desktop
293space most of the time but is quickly available at the press of a key.
294
295The accelerator key is grabbed regardless of any modifiers, so this
296extension will actually grab a physical key just for this function.
297
298If you want a quake-like animation, tell your window manager to do so
299(fvwm can do it).

326We use it to implement a "distributed selection mechanism", which just
327means that one command uploads the file to a remote server, and another
328reads it.
329
330The commands can be set using the C<URxvt.remote-selection.store> and
331C<URxvt.remote-selection.fetch> resources. The first should read the
332selection to store from STDIN (always in UTF-8), the second should provide
333the selection data on STDOUT (also in UTF-8).
334
335The defaults (which are likely useless to you) use rsh and cat:
