		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.

		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

		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:

		246
		247	=item remote-clipboard
		248
		249	Somewhat of a misnomer, this extension adds two menu entries to the
		250	selection popup that allows one ti run external commands to store the
		251	selection somewhere and fetch it again.
		252
		253	We use it to implement a "distributed selection mechanism", which just
		254	means that one command uploads the file to a remote server, and another
		255	reads it.
		256
		257	The commands can be set using the C<URxvt.remote-selection.store> and
		258	C<URxvt.remote-selection.fetch> resources. The first should read the
		259	selection to store from STDIN (always in UTF-8), the second should provide
		260	the selection data on STDOUT (also in UTF-8).
		261
		262	The defaults (which are likely useless to you) use rsh and cat:
		263
		264	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		265	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		266
		267	=item selection-pastebin
		268
		269	This is a little rarely useful extension that Uploads the selection as
		270	textfile to a remote site (or does other things). (The implementation is
		271	not currently secure for use in a multiuser environment as it writes to
		272	F</tmp> directly.).
		273
		274	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		275	i.e.
		276
		277	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		278
		279	Pressing this combination runs a command with C<%> replaced by the name of
		280	the textfile. This command can be set via a resource:
		281
		282	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		283
		284	And the default is likely not useful to anybody but the few people around
		285	here :)
		286
		287	The name of the textfile is the hex encoded md5 sum of the selection, so
		288	the same content should lead to the same filename.
		289
		290	After a successful upload the selection will be replaced by the text given
		291	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		292	for the filename):
		293
		294	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
