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
160
161The normal selection mechanism isn't disabled, so quick successive clicks
162might interfere with selection creation in harmless ways.

199=item tabbed
200
201This transforms the terminal into a tabbar with additional terminals, that
202is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204button per tab.
205
206Clicking a button will activate that tab. Pressing B<Shift-Left> and
207B<Shift-Right> will switch to the tab left or right of the current one,
208while B<Shift-Down> creates a new tab.
209
210The tabbar itself can be configured similarly to a normal terminal, but
211with a resource class of C<URxvt.tabbed>. In addition, it supports the
212following four resources (shown with defaults):
213
214 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
215 URxvt.tabbed.tabbar-bg: <colour-index, default 0>

231This (experimental) perl extension implements OnTheSpot editing. It does
232not work perfectly, and some input methods don't seem to work well with
233OnTheSpot editing in general, but it seems to work at leats for SCIM and
234kinput2.

264
265We use it to implement a "distributed selection mechanism", which just
266means that one command uploads the file to a remote server, and another
267reads it.
268
269The commands can be set using the C<URxvt.remote-selection.store> and
270C<URxvt.remote-selection.fetch> resources. The first should read the
271selection to store from STDIN (always in UTF-8), the second should provide
272the selection data on STDOUT (also in UTF-8).
273
274The defaults (which are likely useless to you) use rsh and cat:
