Launcher is a third-party application written by CanuckInLA that binds to the hijack menu as the only thing running in memory at that time. From that, you can choose to launch any programs you've configured within it.

Here's a thread where I talk about it, but I don't have a link handy for you to download it.

Launcher may have recently become obsoleted by Mark's completion of the Menu_exec feature, but I haven't tried that feature yet so I don't know quite how it works.
