Clear custom command history
Use this option to remove the history of “Custom Commands” you've entered in the collapsed mode that did not match any of the installed application commands.


Custom Actions


Custom actions can be used to match commands entered in the collapsed view and use them to quickly perform tasks.

It can for example be use the make shortcuts to commands, but also to send arguments to a website, for quick searching.

By default 4 custom actions are predefined, but you can change this to anything you like. See also the Custom Action Examples in the dedicated wiki page.


You can add a new (empty) action by clicking on the Add (+) button and remove the selected action by pressing the Delete (x) button.

Strings in the Application Finder by the type and pattern or the action. If there is a match, the command is executed as a replacement for the entered string.

There are two types of pattern matches.
If this type is selected, there is a match if the entered string starts with pattern.
Regular Expression
For complex matches you can write a Perl-compatible regular expression that is matched against the entered string.
Depending on the selected type it will describe the matching prefix or regular expression.
The command that is executed when the pattern is matched. To include (parts) of the match the following variables are available:
Include the string after the matched pattern. So if the prefix-pattern is abc and the entered command abcdef, %s will be replaced with def.
Include the complete string after the matches pattern. So if the prefix-pattern is abc and the entered command abcdef, %s will be replaced with abcdef.
Regular Expression
During the process of matching, the match results of subpattern between parentheses ( ) are recorded for later use. \ plus a number to refer to the corresponding substring. \1 refers to 1st pair of parentheses' match result, \2 refers to 2nd pair of parentheses' match result. A special case is \0 which will be replaced with the entire match.
If the pattern is ^ab(.*)fg$ and the entered command abcdefg, \1 will be replaced with cde.
