132=item readline (enabled by default)
133
134A support package that tries to make editing with readline easier. At the
135moment, it reacts to clicking with the left mouse button by trying to
136move the text cursor to this position. It does so by generating as many
137cursor-left or cursor-right keypresses as required (the this only works
138for programs that correctly support wide characters).
139
140To avoid too many false positives, this is only done when:
141
142=over 4
143
144=item - the mouse is on the same (multi-row-) line as the text cursor.
145
146=item - the primary screen is currently being displayed.
147
148=item - the text cursor is visible.
149
150=back
151
152The normal selection mechanism isn't disabled, so quick successive clicks
153might interfere with selection creation in harmless ways.

192This transforms the terminal into a tabbar with additional terminals, that
