Hey Bob, I have found that the best way to learn new apps is to just dig in and and try to what you want, then google what ever stumps you. I then write it down in a little note book, but I rarely need to go back to the note book 'cause writing it down seems to increase the chance of it getting it in long term memory. You'll find everyone here wants to answer your problem no matter how trivial, unlike many other forums where a simple question can get you some not so easy to understand answers just to belittle your question.
ie...Google> Cakewalk how to activate ripple edit
and the answer magically appears. Otherwise ask here and you will always get good answers and answers to things you thought you knew, but dang if there ain't someone with a better way.
Good Luck
