CSeye has a good point. I'll augment that. What kind of work do you do (or want to do) in Logic? Creating a tempo map for film and working in the score editor have different demands/commands than editing audio.
And, as Logic's commands are customizable, it may make more sense to use ProTools key commands if you have a comfort base there, for example.
You can print the Commands as a PDF, then drag and drop the text for the commands you use most often into a text editor. You can also just type it in, but there is an advantage to dragging the text from the PDF because it preserves all the symbols used to designate the special keys and key modifiers.
Either way, it's about 30 minutes work, and well worth the effort. If you put the sheet in front of you and force yourself to use the key commands at every opportunity, after a few weeks you won't even need the sheet any more.
Printing out the commands was very helpful when I started using L8. Then a few things changed in L9, so I ended up printing out those as well.
Right now I have a 4"x6" index card with 26 handwritten key commands for step entry and score editing based on Doug's Score video tutorial. That significantly reduced the amount of mouse-clicking involved in MIDI mock-ups.
