I understand that your experience is yours but I also believe that you might be going about it the wrong way.
First, you don't REALLY need to know anything but Meta-X and Control-XS, Control-XF, Control-XC to get going. Those aren't really that hard to remember or make muscle memory for, IMO. It IS hard to have to go back a bit to re-integrate how to do things in a new way if you're already happy with your existing workflow, so if there's no value for you, then... don't use it. Use whatever works for you.
