73beginning of a line when they process multiple files. The following
74pattern matches the filename (note, there is a single space at the very

139=item readline (enabled by default)
140
141A support package that tries to make editing with readline easier. At the
142moment, it reacts to clicking with the left mouse button by trying to
143move the text cursor to this position. It does so by generating as many
144cursor-left or cursor-right keypresses as required (the this only works
145for programs that correctly support wide characters).
146
147To 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.

159=back

161The normal selection mechanism isn't disabled, so quick successive clicks
162might interfere with selection creation in harmless ways.

217=item xim-onthespot
218
219This (experimental) perl extension implements OnTheSpot editing. It does
220not work perfectly, and some input methods don't seem to work well with
221OnTheSpot editing in general, but it seems to work at leats for SCIM and
222kinput2.
223
224You enable it by specifying this extension and a preedit style of

252
253We use it to implement a "distributed selection mechanism", which just
254means that one command uploads the file to a remote server, and another
255reads it.
256
257The commands can be set using the C<URxvt.remote-selection.store> and
258C<URxvt.remote-selection.fetch> resources. The first should read the
259selection to store from STDIN (always in UTF-8), the second should provide
260the selection data on STDOUT (also in UTF-8).
261
262The defaults (which are likely useless to you) use rsh and cat:
