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.

132Of course, this can be modified to suit your needs and your editor :) 204Of course, this can be modified to suit your needs and your editor :)
205
206To expand the example above to typical perl error messages ("XXX at
207FILENAME line YYY."), you need a slightly more elaborate solution:
208
209 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
210 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
211
212The first line tells the selection code to treat the unchanging part of
213every error message as a selection pattern, and the second line transforms
214the message into vi commands to load the file.
215
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>
233 URxvt.tabbed.tab-fg: <colour-index, default 0>
234 URxvt.tabbed.tab-bg: <colour-index, default 1>

237indices.

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.

260This is basically a very small extension that dynamically changes the
261background pixmap offset to the window position, in effect creating the
262same effect as pseudo transparency with a custom pixmap. No scaling is
263supported in this mode. Exmaple:

276
277=item remote-clipboard
278
279Somewhat of a misnomer, this extension adds two menu entries to the
280selection popup that allows one ti run external commands to store the
281selection somewhere and fetch it again.
282
283We use it to implement a "distributed selection mechanism", which just
284means that one command uploads the file to a remote server, and another
285reads it.
286
287The commands can be set using the C<URxvt.remote-selection.store> and
288C<URxvt.remote-selection.fetch> resources. The first should read the
289selection to store from STDIN (always in UTF-8), the second should provide
290the selection data on STDOUT (also in UTF-8).
291
292The defaults (which are likely useless to you) use rsh and cat:
293
294 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
295 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
296
297=item selection-pastebin
298
299This is a little rarely useful extension that Uploads the selection as
300textfile to a remote site (or does other things). (The implementation is
301not currently secure for use in a multiuser environment as it writes to
302F</tmp> directly.).
303
304It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
305i.e.
306
307 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
308
309Pressing this combination runs a command with C<%> replaced by the name of
310the textfile. This command can be set via a resource:
311
312 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
313
314And the default is likely not useful to anybody but the few people around
315here :)
316
317The name of the textfile is the hex encoded md5 sum of the selection, so
318the same content should lead to the same filename.
319
320After a successful upload the selection will be replaced by the text given
321in the C<selection-pastebin-url> resource (again, the % is the placeholder
322for the filename):
