109It's sole argument is the popup menu, which can be modified. The selection
110is in C<$_>, which can be used to decide wether to add something or not.

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.

157=item - the mouse is on the same (multi-row-) line as the text cursor.

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:
