The Key Commands either don't respond, or they don't behave as expected.

First thing first: make sure your cursor is pointed at the correct division (window).

Next: make sure you're in the right mode - Some commands only work in Object Mode and some only in Edit Mode. There are actually OTHER MODES you can be in. You may want to see if you're in one of these. Look for the dropdown menu below.

If neither of these works for you, send me an email detailing what's happening and what you've done to try to fix it.
