22FREQUENTLY ASKED QUESTIONS 22FREQUENTLY ASKED QUESTIONS
23 The new selection selects pieces that are too big, how can I select
24 single words?
25 Yes. For example, if you want to select alphanumeric words, you can
26 use the following resource:
27
28 URxvt.selection.pattern-0: ([[:word:]]+)
29
30 If you click more than twice, the selection will be extended more
31 and more.
32
33 To get a selection that is very similar to the old code, try this
34 pattern:
35
36 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
37
38 Please also note that the *LeftClick Shift-LeftClik* combination
39 also selects words like the old code.
40
41 I don't like the new selection/popups/hotkeys/perl, how do I
42 change/disable it?
43 You can disable the perl extension completely by setting the
44 perl-ext-common resource to the empty string, which also keeps
45 rxvt-unicode from initialising perl, saving memory.
46
47 If you only want to disable specific features, you first have to
48 identify which perl extension is responsible. For this, read the
49 section PREPACKAGED EXTENSIONS in the urxvtperl(3) manpage. For
50 example, to disable the selection-popup and option-popup, specify
51 this perl-ext-common resource:
52
53 URxvt.perl-ext-common: default,-selection-popup,-option-popup
54
55 This will keep the default extensions, but disable the two popup
56 extensions. Some extensions can also be configured, for example,
57 scrollback search mode is triggered by M-s. You can move it to any
58 other combination either by setting the searchable-scrollback
59 resource:
60
61 URxvt.searchable-scrollback: CM-s
62
23 Isn't rxvt supposed to be small? Don't all those features bloat? 63 Isn't rxvt supposed to be small? Don't all those features bloat?

25 extra bloat. If you compare a minimal rxvt and a minimal urxvt, you 65 extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
