157get a case-sensitive search you can delete this prefix using C<BackSpace>
158or simply use an uppercase character which removes the "(?i)" prefix.

160See L<perlre> for more info about perl regular expression syntax.

162=item readline (enabled by default)
163
164A support package that tries to make editing with readline easier. At
165the moment, it reacts to clicking shift-left mouse button by trying to
166move the text cursor to this position. It does so by generating as many
167cursor-left or cursor-right keypresses as required (the this only works
168for programs that correctly support wide characters).
169
170To avoid too many false positives, this is only done when:
171
172=over 4
173
174=item - the tty is in ICANON state.
175
176=item - the text cursor is visible.
177
178=item - the primary screen is currently being displayed.
179
180=item - the mouse is on the same (multi-row-) line as the text cursor.
181
182=back
183
184The normal selection mechanism isn't disabled, so quick successive clicks
185might interfere with selection creation in harmless ways.

222=item tabbed
223
224This transforms the terminal into a tabbar with additional terminals, that
225is, it implements what is commonly refered to as "tabbed terminal". The topmost line
226displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
227button per tab.
228
229Clicking a button will activate that tab. Pressing B<Shift-Left> and
230B<Shift-Right> will switch to the tab left or right of the current one,
231while B<Shift-Down> creates a new tab.
232
233The tabbar itself can be configured similarly to a normal terminal, but
234with a resource class of C<URxvt.tabbed>. In addition, it supports the
235following four resources (shown with defaults):
236
237 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
238 URxvt.tabbed.tabbar-bg: <colour-index, default 0>

254This (experimental) perl extension implements OnTheSpot editing. It does
255not work perfectly, and some input methods don't seem to work well with
256OnTheSpot editing in general, but it seems to work at leats for SCIM and
257kinput2.

288
289We use it to implement a "distributed selection mechanism", which just
290means that one command uploads the file to a remote server, and another
291reads it.
292
293The commands can be set using the C<URxvt.remote-selection.store> and
294C<URxvt.remote-selection.fetch> resources. The first should read the
295selection to store from STDIN (always in UTF-8), the second should provide
296the selection data on STDOUT (also in UTF-8).
