Update by JMS for the hotkey script.

Also made some changes
- fly mode keys have changed and added snap key
- using "i=list.index(val)" is slow, use "for i,val in enumerate(list)" instead.
- dont use "i in range(start, end)" - silly to make a list when you can do "min < val < max"

JMS, please update from this version.
