29=item The new selection selects pieces that are too big, how can I select
30single words?
31
32Yes. For example, if you want to select alphanumeric words, you can use
33the following resource:
34
35 URxvt.selection.pattern-0: ([[:word:]]+)
36
37If you click more than twice, the selection will be extended
38more and more.
39
40To get a selection that is very similar to the old code, try this pattern:
41
42 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
43
44Please also note that the I<LeftClick Shift-LeftClik> combination also
45selects words like the old code.
46
47=item I don't like the new selection/popups/hotkeys/perl, how do I
48change/disable it?
49
50You can disable the perl extension completely by setting the
51B<perl-ext-common> resource to the empty string, which also keeps
52rxvt-unicode from initialising perl, saving memory.
53
54If you only want to disable specific features, you first have to
55identify which perl extension is responsible. For this, read the section
56B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57example, to disable the B<selection-popup> and B<option-popup>, specify
58this B<perl-ext-common> resource:
59
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup
61
62This will keep the default extensions, but disable the two popup
63extensions. Some extensions can also be configured, for example,
64scrollback search mode is triggered by B<M-s>. You can move it to any
65other combination either by setting the B<searchable-scrollback> resource:
66
67 URxvt.searchable-scrollback: CM-s
