94Other extensions can extend this popup menu by pushing a code reference onto
95C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed.
96
97It's sole argument is the popup menu, which can be modified. The selection
98is in C<$_>, which can be used to decide wether to add something or not.
99It should either return nothing or a string and a code reference. The
100string will be used as button text and the code reference will be called
101when the button gets activated and should transform C<$_>.

103The following will add an entry C<a to b> that transforms all C<a>s in

169=item automove-background
170
171This is basically a one-line extension that dynamically changes the background pixmap offset
172to the window position, in effect creating the same effect as pseudo transparency with
173a custom pixmap. No scaling is supported in this mode. Exmaple:

193=item selection-pastebin
194
195This is a little rarely useful extension that Uploads the selection as
196textfile to a remote site (or does other things). (The implementation is
197not currently secure for use in a multiuser environment as it writes to
198F</tmp> directly.).
199
200It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
201i.e.
202
203 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
204
205Pressing this combination runs a command with C<%> replaced by the name of
206the textfile. This command can be set via a resource:
207
208 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
209
210And the default is likely not useful to anybody but the few people around
211here :)
212
213The name of the textfile is the hex encoded md5 sum of the selection, so
214the same content should lead to the same filename.
215
216After a successful upload the selection will be replaced by the text given
217in the C<selection-pastebin-url> resource (again, the % is the placeholder
218for the filename):
