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.

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.

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.

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).

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).
