76	=item searchable-scrollback<hotkey> (enabled by default)
77
78	Adds regex search functionality to the scrollback buffer, triggered
79	by a hotkey (default: C<M-s>). While in search mode, normal terminal
80	input/output is suspended and a regex is displayed at the bottom of the
81	screen.

84	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
85	search upwards/downwards in the scrollback buffer, C<End> jumps to the
86	bottom. C<Escape> leaves search mode and returns to the point where search
87	was started, while C<Enter> or C<Return> stay at the current position and
