Keyboard shortcuts editable? Numeric keyboard?

[Tam]

Hi all
I'm looking forward to a USB-numeric-keyboard to have access to "my favorites" in Forte4:
Scene up/down (already okay +/-), but also select/browse/scroll scenes/songs/sets etc.

A small USB-MIDI-keyboard could do the same job, but needs little more space on top of my organ.
(Don't want to place my laptop there.)

In both cases key-shortcuts (or MIDI-assignment) must be more flexible.

Please let me know if I missed some information.
best regards
Tam
