2 The new selection selects pieces that are too big, how can I select
3 single words?
4 Yes. For example, if you want to select alphanumeric words, you can
5 use the following resource:
6
7 URxvt.selection.pattern-0: ([[:word:]]+)
8
9 If you click more than twice, the selection will be extended more
10 and more.
11
12 To get a selection that is very similar to the old code, try this
13 pattern:
14
15 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
16
17 Please also note that the *LeftClick Shift-LeftClik* combination
18 also selects words like the old code.
19
20 I don't like the new selection/popups/hotkeys/perl, how do I
21 change/disable it?
22 You can disable the perl extension completely by setting the
23 perl-ext-common resource to the empty string, which also keeps
24 rxvt-unicode from initialising perl, saving memory.
25
26 If you only want to disable specific features, you first have to
27 identify which perl extension is responsible. For this, read the
28 section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
29 example, to disable the selection-popup and option-popup, specify
30 this perl-ext-common resource:
31
32 URxvt.perl-ext-common: default,-selection-popup,-option-popup
33
34 This will keep the default extensions, but disable the two popup
35 extensions. Some extensions can also be configured, for example,
36 scrollback search mode is triggered by M-s. You can move it to any
37 other combination either by setting the searchable-scrollback
38 resource:
39
40 URxvt.searchable-scrollback: CM-s

185 privileges immediately. This is much safer than most other terminals

144 So, while setuid/setgid operation is supported and not a problem on
