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.

264It is possible to activate the most recently seen match or a list of matches

326=item remote-clipboard
327
328Somewhat of a misnomer, this extension adds two menu entries to the
329selection popup that allows one to run external commands to store the
330selection somewhere and fetch it again.
331
332We use it to implement a "distributed selection mechanism", which just
333means that one command uploads the file to a remote server, and another
334reads it.
335
336The commands can be set using the C<URxvt.remote-selection.store> and
337C<URxvt.remote-selection.fetch> resources. The first should read the
338selection to store from STDIN (always in UTF-8), the second should provide
339the selection data on STDOUT (also in UTF-8).
340
341The defaults (which are likely useless to you) use rsh and cat:
342
343 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
344 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
345
346=item selection-pastebin
347
348This is a little rarely useful extension that uploads the selection as
349textfile to a remote site (or does other things). (The implementation is
350not currently secure for use in a multiuser environment as it writes to
351F</tmp> directly.).
352
353It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
354i.e.
355
356 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
357
358Pressing this combination runs a command with C<%> replaced by the name of
359the textfile. This command can be set via a resource:
360
361 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
362
363And the default is likely not useful to anybody but the few people around
364here :)
365
366The name of the textfile is the hex encoded md5 sum of the selection, so
367the same content should lead to the same filename.
368
369After a successful upload the selection will be replaced by the text given
370in the C<selection-pastebin-url> resource (again, the % is the placeholder
371for the filename):

387 URxvt.keysym.M-v: perl:macosx-clipboard:paste
388
389The difference between them is that the native variant requires a
390perl from apple's devkit or so, and C<macosx-clipboard> requires the
391C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
392simpler etc. etc.
