117 readline (enabled by default)
118 A support package that tries to make editing with readline easier.
119 At the moment, it reacts to clicking with the left mouse button by
120 trying to move the text cursor to this position. It does so by
121 generating as many cursor-left or cursor-right keypresses as
122 required (the this only works for programs that correctly support
123 wide characters).
124
125 To avoid too many false positives, this is only done when:
126
127 - the tty is in ICANON state.
128 - the text cursor is visible.
129 - the primary screen is currently being displayed.
130 - the mouse is on the same (multi-row-) line as the text cursor.

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

170 tabbed
171 This transforms the terminal into a tabbar with additional
172 terminals, that is, it implements what is commonly refered to as
173 "tabbed terminal". The topmost line displays a "[NEW]" button,
174 which, when clicked, will add a new tab, followed by one button per
175 tab.
176
177 Clicking a button will activate that tab. Pressing Shift-Left and
178 Shift-Right will switch to the tab left or right of the current one,
179 while Shift-Down creates a new tab.

485 @urxvt::TERM_INIT
486 All coderefs in this array will be called as methods of the next
487 newly created "urxvt::term" object (during the "on_init" phase). The
488 array gets cleared before the codereferences that were in it are
489 being executed, so coderefs can push themselves onto it again if
490 they so desire.

492 This complements to the perl-eval commandline option, but gets
493 executed first.
