@User: It would probably be very helpful to distribute two (or more) sets of key bindings with Magic and let a user choose between them with a command-line option, like you can do for choosing the techfile or the graphics interface.

@Tim Edwards I would suggest to enhance magic to just run several tcl scripts on the commandline, that way you could load the techfile, change the keybindings, and even run a generator script, just by adding those 3 scrips on the commandline. Just execute them in the order they are given.
