|
10 | searchable-scrollback<hotkey> - incremental scrollback search (enabled by default) |
|
|

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