98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.

102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.
107
108The following will add an entry C<a to b> that transforms all C<a>s in
109the selection to C<b>s, but only if the selection currently contains any

132=item readline (enabled by default)
133
134A support package that tries to make editing with readline easier. At the
135moment, it reacts to clicking with the left mouse button by trying to
136move the text cursor to this position. It does so by generating as many
137cursor-left or cursor-right keypresses as required (the this only works
138for programs that correctly support wide characters).
139
140To avoid too many false positives, this is only done when:
141
142=over 4
143
144=item - the mouse is on the same (multi-row-) line as the text cursor.
145
146=item - the primary screen is currently being displayed.
147
148=item - the text cursor is visible.

152The normal selection mechanism isn't disabled, so quick successive clicks
153might interfere with selection creation in harmless ways.

232=item selection-pastebin
233
234This is a little rarely useful extension that Uploads the selection as
235textfile to a remote site (or does other things). (The implementation is
236not currently secure for use in a multiuser environment as it writes to
237F</tmp> directly.).
238
239It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
240i.e.
241
242 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
243
244Pressing this combination runs a command with C<%> replaced by the name of
245the textfile. This command can be set via a resource:
246
247 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
248
249And the default is likely not useful to anybody but the few people around
250here :)
251
252The name of the textfile is the hex encoded md5 sum of the selection, so
253the same content should lead to the same filename.
254
255After a successful upload the selection will be replaced by the text given
256in the C<selection-pastebin-url> resource (again, the % is the placeholder
257for the filename):
