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.

86	bottom. C<Escape> leaves search mode and returns to the point where search
