To use 5 Nav Launcher install fnl.prc and then bind it to one of your hard keys using the Palm preferences.

Holding down a direction on the 5 way navigator will cycle through four slots corresponding to that application, a single application may be bound to the central select button on the 5 way navigator, or another application may be launched if you dont press any keys for a period of time.

If you want to launch even more applications you can use additional 5 Nav Launcher "shortcuts", each of which adds another 18 launchable applications.
