176This is basically a one-line extension that dynamically changes the background pixmap offset
177to the window position, in effect creating the same effect as pseudo transparency with

198=item selection-pastebin
199
200This is a little rarely useful extension that Uploads the selection as
201textfile to a remote site (or does other things). (The implementation is
202not currently secure for use in a multiuser environment as it writes to
203F</tmp> directly.).
204
205It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
206i.e.
207
208 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
209
210Pressing this combination runs a command with C<%> replaced by the name of
211the textfile. This command can be set via a resource:
212
213 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
214
215And the default is likely not useful to anybody but the few people around
216here :)
217
218The name of the textfile is the hex encoded md5 sum of the selection, so
219the same content should lead to the same filename.
220
221After a successful upload the selection will be replaced by the text given
222in the C<selection-pastebin-url> resource (again, the % is the placeholder
223for the filename):
