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

174
175It only works when clicking into the same line (possibly extended over
176multiple rows) as the text cursor and on the primary screen, to reduce the

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.

274not work perfectly, and some input methods don't seem to work well with
275OnTheSpot editing in general, but it seems to work at leats for SCIM and
276kinput2.

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

300(fvwm can do it).

326
327We use it to implement a "distributed selection mechanism", which just
328means that one command uploads the file to a remote server, and another
329reads it.
330
331The commands can be set using the C<URxvt.remote-selection.store> and
332C<URxvt.remote-selection.fetch> resources. The first should read the
333selection to store from STDIN (always in UTF-8), the second should provide
334the selection data on STDOUT (also in UTF-8).
335
336The defaults (which are likely useless to you) use rsh and cat:
