Today I learned more patience than I should ever have needed. Today I used Maya to edit animations.
Here are my suggestions for improving your time when working with Maya for editing character animations in Time Editor (by command)
Copy. Read a couple chapters of a books.
Paste. Take a nap.
Split Clip at Current Frame. Go to a theatre and watch a movie.
Bake to New Clip. Enjoy a good meal with a friend.
