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.
35 36
37The C<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
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.
67
68=item C<y>
69
70Copy the current match to the clipboard.
71
72=back
73
74It is also possible to cycle through the matches using a key
75combination bound to the C<matcher:select> action.

91=head2 Regex encoding/wide character matching
92
93Urxvt stores all text as unicode, in a special encoding that uses
94one character/code point per column. For various reasons, the regular
95expressions are matched directly against this encoding, which means there are a few things
96you need to keep in mind:
97
98=over
99
100=item X resources/command line arguments are locale-encoded
101
102The regexes taken from the command line or resources will be converted
103from locale encoding to unicode. This can change the number of code points
104per character.
105
106=item Wide characters are column-padded with C<$urxvt::NOCHAR>
107
108Wide characters (such as kanji and sometimes tabs) are padded with
109a special character value (C<$urxvt::NOCHAR>). That means that
110constructs such as C<\w> or C<.> will only match part of a character, as
111C<$urxvt::NOCHAR> is not matched by C<\w> and both only match the first
112"column" of a wide character.
113
114That means you have to incorporate C<$urxvt::NOCHAR> into parts of regexes
115that may match wide characters. For example, to match C<\w+> you might
116want to use C<[\w$urxvt::NOCHAR]+> instead, and to match a single character
117(C<.>) you might want to use C<.$urxvt::NOCHAR*> instead.
