156=item readline (enabled by default)
157
158A support package that tries to make editing with readline easier. At
159the moment, it reacts to clicking shift-left mouse button by trying to
160move the text cursor to this position. It does so by generating as many
161cursor-left or cursor-right keypresses as required (the this only works
162for programs that correctly support wide characters).
163
164To avoid too many false positives, this is only done when:
165
166=over 4
167
168=item - the tty is in ICANON state.
169
170=item - the text cursor is visible.
171
172=item - the primary screen is currently being displayed.
173
174=item - the mouse is on the same (multi-row-) line as the text cursor.

177
178The normal selection mechanism isn't disabled, so quick successive clicks
179might interfere with selection creation in harmless ways.

216=item tabbed
217
218This transforms the terminal into a tabbar with additional terminals, that
219is, it implements what is commonly refered to as "tabbed terminal". The topmost line
220displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
221button per tab.
222
223Clicking a button will activate that tab. Pressing B<Shift-Left> and
224B<Shift-Right> will switch to the tab left or right of the current one,
225while B<Shift-Down> creates a new tab.
226
227The tabbar itself can be configured similarly to a normal terminal, but
228with a resource class of C<URxvt.tabbed>. In addition, it supports the
229following four resources (shown with defaults):
230
231 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
232 URxvt.tabbed.tabbar-bg: <colour-index, default 0>

247
248This (experimental) perl extension implements OnTheSpot editing. It does
249not work perfectly, and some input methods don't seem to work well with
250OnTheSpot editing in general, but it seems to work at leats for SCIM and
251kinput2.

276=item remote-clipboard
277
278Somewhat of a misnomer, this extension adds two menu entries to the
279selection popup that allows one ti run external commands to store the
280selection somewhere and fetch it again.
281
282We use it to implement a "distributed selection mechanism", which just
283means that one command uploads the file to a remote server, and another
284reads it.
285
286The commands can be set using the C<URxvt.remote-selection.store> and
287C<URxvt.remote-selection.fetch> resources. The first should read the
288selection to store from STDIN (always in UTF-8), the second should provide
289the selection data on STDOUT (also in UTF-8).
290
291The defaults (which are likely useless to you) use rsh and cat:
292
293 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
294 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
295
296=item selection-pastebin
297
298This is a little rarely useful extension that Uploads the selection as
299textfile to a remote site (or does other things). (The implementation is
300not currently secure for use in a multiuser environment as it writes to
301F</tmp> directly.).
302
303It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
304i.e.
305
306 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
307
308Pressing this combination runs a command with C<%> replaced by the name of
309the textfile. This command can be set via a resource:
310
311 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
312
313And the default is likely not useful to anybody but the few people around
314here :)
315
316The name of the textfile is the hex encoded md5 sum of the selection, so
317the same content should lead to the same filename.
318
319After a successful upload the selection will be replaced by the text given
320in the C<selection-pastebin-url> resource (again, the % is the placeholder
321for the filename):
