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 rxvtperl(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 |
|
|
