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

		108
		109	It's sole argument is the popup menu, which can be modified. The selection
		110	is in C<$_>, which can be used to decide wether to add something or not.
		111	It should either return nothing or a string and a code reference. The
		112	string will be used as button text and the code reference will be called
		113	when the button gets activated and should transform C<$_>.
		114
		115	The following will add an entry C<a to b> that transforms all C<a>s in

		139	=item readline (enabled by default)
		140
		141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).
		146
		147	To avoid too many false positives, this is only done when:
		148
		149	=over 4
		150
		151	=item - the tty is in ICANON state.
		152
		153	=item - the text cursor is visible.
		154
		155	=item - the primary screen is currently being displayed.
		156
		157	=item - the mouse is on the same (multi-row-) line as the text cursor.
		158
		159	=back
		160
		161	The normal selection mechanism isn't disabled, so quick successive clicks
		162	might interfere with selection creation in harmless ways.

		186
		187	Of course, this can be modified to suit your needs and your editor :)
		188
		189	To expand the example above to typical perl error messages ("XXX at
		190	FILENAME line YYY."), you need a slightly more elaborate solution:
		191
		192	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		193	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		194
		195	The first line tells the selection code to treat the unchanging part of
		196	every error message as a selection pattern, and the second line transforms
		197	the message into vi commands to load the file.
		198
		199	=item tabbed
		200
		201	This transforms the terminal into a tabbar with additional terminals, that
		202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		204	button per tab.
		205
		206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		207	B<Shift-Right> will switch to the tab left or right of the current one,
		208	while B<Shift-Down> creates a new tab.

138		216
		217	=item xim-onthespot
		218
		219	This (experimental) perl extension implements OnTheSpot editing. It does
		220	not work perfectly, and some input methods don't seem to work well with
		221	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		222	kinput2.
		223
		224	You enable it by specifying this extension and a preedit style of
		225	C<OnTheSpot>, i.e.:
		226
		227	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		228
		229	=item automove-background
		230
		231	This is basically a one-line extension that dynamically changes the background pixmap offset
		232	to the window position, in effect creating the same effect as pseudo transparency with
		233	a custom pixmap. No scaling is supported in this mode. Exmaple:
		234

		252
		253	=item selection-pastebin
		254
		255	This is a little rarely useful extension that Uploads the selection as
		256	textfile to a remote site (or does other things). (The implementation is
		257	not currently secure for use in a multiuser environment as it writes to
		258	F</tmp> directly.).
		259
		260	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		261	i.e.
		262
		263	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		264
		265	Pressing this combination runs a command with C<%> replaced by the name of
		266	the textfile. This command can be set via a resource:
		267
		268	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		269
		270	And the default is likely not useful to anybody but the few people around
		271	here :)
		272
		273	The name of the textfile is the hex encoded md5 sum of the selection, so
		274	the same content should lead to the same filename.
		275
		276	After a successful upload the selection will be replaced by the text given
		277	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		278	for the filename):
		279
		280	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
