94Other extensions can extend this popup menu by pushing a code reference
95onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
96popup is displayed.

98It's sole argument is the popup menu, which can be modified. The selection
99is in C<$_>, which can be used to decide wether to add something or not.
100It should either return nothing or a string and a code reference. The
101string will be used as button text and the code reference will be called
102when the button gets activated and should transform C<$_>.

170=item automove-background
171
172This is basically a one-line extension that dynamically changes the background pixmap offset
173to the window position, in effect creating the same effect as pseudo transparency with
174a custom pixmap. No scaling is supported in this mode. Exmaple:

194=item selection-pastebin
195
196This is a little rarely useful extension that Uploads the selection as
197textfile to a remote site (or does other things). (The implementation is
198not currently secure for use in a multiuser environment as it writes to
199F</tmp> directly.).
200
201It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
202i.e.
203
204 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
205
206Pressing this combination runs a command with C<%> replaced by the name of
207the textfile. This command can be set via a resource:
208
209 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
210
211And the default is likely not useful to anybody but the few people around
212here :)
213
214The name of the textfile is the hex encoded md5 sum of the selection, so
215the same content should lead to the same filename.
216
217After a successful upload the selection will be replaced by the text given
218in the C<selection-pastebin-url> resource (again, the % is the placeholder
219for the filename):
