58 be used for the match. For example, the followign adds a regex that 58 be used for the match. For example, the followign adds a regex that
59 matches everything between two vertical bars: 59 matches everything between two vertical bars:

61 URxvt.selection.pattern-0: \\|([^|]+)\\| 61 URxvt.selection.pattern-0: \\|([^|]+)\\|
62 62
63 Another example: Programs I use often output "absolute path: " at
64 the beginning of a line when they process multiple files. The
65 following pattern matches the filename (note, there is a single
66 space at the very end):

124 readline (enabled by default)
125 A support package that tries to make editing with readline easier.
126 At the moment, it reacts to clicking with the left mouse button by
127 trying to move the text cursor to this position. It does so by
128 generating as many cursor-left or cursor-right keypresses as
129 required (the this only works for programs that correctly support
130 wide characters).
131
132 To avoid too many false positives, this is only done when:
133
134 - the tty is in ICANON state.
135 - the text cursor is visible.
136 - the primary screen is currently being displayed.
137 - the mouse is on the same (multi-row-) line as the text cursor.
138
139 The normal selection mechanism isn't disabled, so quick successive
140 clicks might interfere with selection creation in harmless ways.

159 Clicking a button will activate that tab. Pressing Shift-Left and 184 Clicking a button will activate that tab. Pressing Shift-Left and
160 Shift-Right will switch to the tab left or right of the current one. 185 Shift-Right will switch to the tab left or right of the current one,
186 while Shift-Down creates a new tab.
187
188 The tabbar itself can be configured similarly to a normal terminal,
189 but with a resource class of "URxvt.tabbed". In addition, it
190 supports the following four resources (shown with defaults):
191
192 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
193 URxvt.tabbed.tabbar-bg: <colour-index, default 0>

205 xim-onthespot
206 This (experimental) perl extension implements OnTheSpot editing. It
207 does not work perfectly, and some input methods don't seem to work
208 well with OnTheSpot editing in general, but it seems to work at
209 leats for SCIM and kinput2.
210

236
237 We use it to implement a "distributed selection mechanism", which
238 just means that one command uploads the file to a remote server, and
239 another reads it.
240
241 The commands can be set using the "URxvt.remote-selection.store" and
242 "URxvt.remote-selection.fetch" resources. The first should read the
243 selection to store from STDIN (always in UTF-8), the second should
244 provide the selection data on STDOUT (also in UTF-8).
245
246 The defaults (which are likely useless to you) use rsh and cat:
247
248 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
