98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.
101
102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.

167=item readline
168
169A support package that tries to make editing with readline easier. At the
170moment, it reacts to clicking with the left mouse button by trying to
171move the text cursor to this position. It does so by generating as many
172cursor-left or cursor-right keypresses as required (the this only works
173for programs that correctly support wide characters).
174
175It only works when clicking into the same line (possibly extended over
176multiple rows) as the text cursor and on the primary screen, to reduce the
177risk of misinterpreting. The normal selection isn't disabled, so quick
178successive clicks might interfere with selection creation in harmless
179ways.
180
181=item tabbed
182
183This transforms the terminal into a tabbar with additional terminals, that
184is, it implements what is commonly refered to as "tabbed terminal". The topmost line
185displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
186button per tab.
187
188Clicking a button will activate that tab. Pressing B<Shift-Left> and
189B<Shift-Right> will switch to the tab left or right of the current one,
190while B<Shift-Down> creates a new tab.

200
201This is basically a one-line extension that dynamically changes the background pixmap offset
202to the window position, in effect creating the same effect as pseudo transparency with
203a custom pixmap. No scaling is supported in this mode. Exmaple:
