Modify hotkeys (shortcuts)

I would like to modify shortcut keys for Pan frame (currently “X”) and Zoom frame (cuurently “Z”)
Seems this is not an option in preferences and am wondering if it is possible some way.
Is maddening as I am roto’ing in flame, then mocha, then flame etc.
I would like ot set mocha to mimic flame.

You can switch around some of our keyframes in mocha in the preferences dialogue inside of mocha. However, I think these two keys are currently static. I can put in a feature request for you.
