33from the keyboard. Simply bind a keysym to "perl:matcher:last" or 33from the keyboard. Simply bind a keysym to "matcher:last" or

36The 'matcher:select' action enables a mode in which it is possible to
37iterate over the matches using the keyboard and either activate them
38or copy them to the clipboard. While the mode is active, normal terminal
39input/output is suspended and the following bindings are recognized:
40
41=over 4
42
43=item C<Up>
44
45Search for a match upwards.
46
47=item C<Down>
48
49Search for a match downwards.
50
51=item C<Home>
52
53Jump to the topmost match.
54
55=item C<End>
56
57Jump to the bottommost match.
58
59=item C<Escape>
60
61Leave the mode and return to the point where search was started.

65Activate the current match.
