What I generally do is start watching the program, hit 'M' for menu, hit 'Enter' to edit the recording, hit 'Z' to load the cut list, and start refining. PgDn and PgUp step you forward and backward through existing cut points. 'Enter' will bring up the action menu ('Esc' will get you out with no action) where you can select what to do. 'Up' and 'Down' arrows let you select how much the 'Right' and 'Left' arrows move you. The rest should be clear with some experimentation.
