Have been looking at ways to map keyboard shortcuts to mouse button three.

I have seen a bit of software that can do this, but was wondering if there was a command line, or edit of a config file that I can use to do this directly.

I am thinking of the Deja Menu app. Using System Preferences and keyboard and mouse options you can use 'Other' on button three to to select other apps to launch.

In the case of Deja Menu, this brings up the Deja Menu config menu rather than the results of using the Deja Menu keyboard shortcut.

SO is there a config file anyway that can be edited directly to achieve this?
