100popup is displayed.

102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.

105string will be used as button text and the code reference will be called

169This transforms the terminal into a tabbar with additional terminals, that

171displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
172button per tab.

174Clicking a button will activate that tab. Pressing B<Shift-Left> and
175B<Shift-Right> will switch to the tab left or right of the current one,

186
187This is basically a one-line extension that dynamically changes the background pixmap offset
188to the window position, in effect creating the same effect as pseudo transparency with
189a custom pixmap. No scaling is supported in this mode. Exmaple:

209=item selection-pastebin
210
211This is a little rarely useful extension that Uploads the selection as
212textfile to a remote site (or does other things). (The implementation is
213not currently secure for use in a multiuser environment as it writes to
214F</tmp> directly.).
215
216It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
217i.e.
218
219 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
220
221Pressing this combination runs a command with C<%> replaced by the name of
222the textfile. This command can be set via a resource:
223
224 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
225
226And the default is likely not useful to anybody but the few people around
227here :)
228
229The name of the textfile is the hex encoded md5 sum of the selection, so
230the same content should lead to the same filename.
231
232After a successful upload the selection will be replaced by the text given
233in the C<selection-pastebin-url> resource (again, the % is the placeholder
234for the filename):
