32It is possible to activate the most recently seen match or a list of matches 33It is possible to activate the most recently seen match or a list of matches
33from the keyboard. Simply bind a keysym to "matcher:last" or 34from the keyboard. Simply bind a keysym to "matcher:last" or
34"matcher:list" as seen in the example below. 35"matcher:list" as seen in the example below.
36
37The 'matcher:select' action enables a mode in which it is possible to
38iterate over the matches using the keyboard and either activate them
39or copy them to the clipboard. While the mode is active, normal terminal
40input/output is suspended and the following bindings are recognized:
41
42=over 4
43
44=item C<Up>
45
46Search for a match upwards.
47
48=item C<Down>
49
50Search for a match downwards.
51
52=item C<Home>
53
54Jump to the topmost match.
55
56=item C<End>
57
58Jump to the bottommost match.
59
60=item C<Escape>
61
62Leave the mode and return to the point where search was started.
63
64=item C<Enter>
65
66Activate the current match.
