10searchable-scrollback<hotkey> - incremental scrollback search (enabled by default)
11
12=head1 DESCRIPTION
13
14Adds regex search functionality to the scrollback buffer, triggered
15by a hotkey (default: C<M-s>). While in search mode, normal terminal
16input/output is suspended and a regex is displayed at the bottom of the
17screen.
18
19Inputting characters appends them to the regex and continues incremental
20search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
21search upwards/downwards in the scrollback buffer, C<End> jumps to the
22bottom. C<Escape> leaves search mode and returns to the point where search
23was started, while C<Enter> or C<Return> stay at the current position and
24additionally stores the first match in the current line into the primary
25selection if the C<Shift> modifier is active.
26
27The regex defaults to "(?i)", resulting in a case-insensitive search. To
28get a case-sensitive search you can delete this prefix using C<BackSpace>
29or simply use an uppercase character which removes the "(?i)" prefix.
30
31See L<perlre> for more info about perl regular expression syntax.
