=head1 DESCRIPTION |
| 19 |
|
|
|
| 20 |
|
|
Add support for evaluating arbitrary perl code using actions in keysym |
| 21 |
|
|
resources. If a keysym I<action> takes the form C<eval:STRING>, the |
| 22 |
|
|
specified B<STRING> is evaluated as a Perl expression. While the full |
| 23 |
|
|
urxvt API is available, the following methods are also provided for |
| 24 |
|
|
users' convenience, as they implement basic actions: |
