This shows the list of applications added to this menu through the Apps tab of Preferences or when executed within Plugin Commander. Selecting one of the items will start the appropriate application. If a "%1" is appended to the application name, the currently selected file in File View will be passed to the application as a parameter. So you can use this menu to start image applications or to display files selected in Plugin Commander with an external application.

Selecting Edit Application List at the top of this list will display the Apps tab of the Preferences dialog for editing the application list.
