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

161=item mark-urls 225=item tabbed
162 226
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.

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
282C<OnTheSpot>, i.e.:

285
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:

327
328=item remote-clipboard
329
330Somewhat of a misnomer, this extension adds two menu entries to the
331selection popup that allows one ti run external commands to store the
332selection somewhere and fetch it again.
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:
344
345 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
346 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
347
348=item selection-pastebin
349
350This is a little rarely useful extension that Uploads the selection as
351textfile to a remote site (or does other things). (The implementation is
352not currently secure for use in a multiuser environment as it writes to
353F</tmp> directly.).
354
355It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
356i.e.
357
358 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
359
360Pressing this combination runs a command with C<%> replaced by the name of
361the textfile. This command can be set via a resource:
362
363 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
364
365And the default is likely not useful to anybody but the few people around
366here :)
367
368The name of the textfile is the hex encoded md5 sum of the selection, so
369the same content should lead to the same filename.
370
371After a successful upload the selection will be replaced by the text given
372in the C<selection-pastebin-url> resource (again, the % is the placeholder
373for the filename):
374
375 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
376
377I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
378the double C</> characters as comment start. Use C<\057\057> instead,
379which works regardless of wether xrdb is used to parse the resource file
380or not.
