Review the section in the manual on training and know-how, for acquiring new skills. Alternate between mental and real time practice of the skill you are trying to learn. Mental training means training the brain by visualizing yourself performing the skill.
Remember, with anything new you want to learn how to "do," one part of your brain needs to learn to do it by building the neural pathways, while the other part of your brain has to learn to coordinate the specific muscles that you'll use.
Keep in mind that a few short sessions, switching back and forth between real time and mental rehearsal, is more effective than one long session.
