On the Actions page, double-click the regular expression or action that you want to edit or select it and press the Edit Action button. A dialog will appear in which the expression text can be edited as you wish.

Click the Add Action... button to add a regular expression for Klipper to match. Klipper uses Qt™'s QRegularExpression, which uses PCRE (Perl Compatible Regular Expressions).

You can add a description of the regular expression type (e.g. “HTTP URL”) by left clicking in the Description column.

Edit the regular expression as described above. To add a command to execute, click Add Command and edit the command in an in-place text editing box. Double-clicking on a command allows you to edit it.

Note that %s in the command line is replaced with the clipboard contents, e.g. if your command definition is kwrite %s and your clipboard contents are /home/phil/textfile, the command kwrite /home/phil/textfile will be run. To include %s in the command line, escape it with a backslash, as so: \%s.

Entries %0 through %9 will be replaced by the corresponding captured texts from the match pattern.
