Hot Keys are not configurable at runtime (you could change the source code though...)
The above descriptions assume you are using a keyboard for an IBM pc or compatable. But different keyboard vendors label their keys differently and different versions of X may map them differently.
I am aware of the following significant differences:
PfaEdit will attempt to guess what keyboard you are using and produce menus with hot-key indicators that match the host machine. If you are displaying on a different machine from the one you are running on the menu names may be wrong. You can fix this up with the keyboard resource, or the -keyboard command line argument.
