So for example, if the menu or directory deals with commands involving quaternions, you could have the * key do quaternion multiplication.

Or is this more the province of the fabled Forms engine?

Thinking about it some more, you could get this behavior in directories by having a global key definition that calls a program variable. But it still wouldn't work in temporary menus.

Interesting.
What is possible right now and would work quite well is to override the key globally. The handler would check the active menu number (with RCLMENU) and provide the new behavior only if the proper menu is active, otherwise chain to the previous handler.
