Pendant ?

Hi Gang,
I'm in the middle of a muddle trying to think of what a pendant
ought to have as a minimum plus some handy controls.
I have sawed the numb key pad off an old 101 keyboard and will
mount it in a panel with PB switches under, re-engraving the keytops.
1 thru 9 (may not use 5) Wide 0 and delete.

Besides the usual axis jogs:
Estop.
Home?
Jog Rate? (push button cycle thru selection)

Estop seems too easy to hit. I can rotate the pad 180°.
What do the folks that use these everyday find as necessary?
