=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: |
