I wanted to add 5-way navigator to my program, only to realize that finding info on it was more of a wild goose chase, PalmSource seems to have nothing I can find. You'd think a new feature would be advertised to developers (more developers who use it will make the hardware more valuable). so I'm asking here to see where it will get me, otherwise I'll just use the standard Palm OS forums...

Anything else that could be useful
For example, can you press two navigator buttons at once to go in a "diagonal" direction?
you can add an FNAV resource to your app specifying the order in which to select the various controls. alternatively, use the APIs FrmSetNavState/FrmSetNavOrder/etc...
