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