If you have enough time and a laptop or tablet at hand, you can also make a sortable table with all the Matrix Actions, with each one row for: Time needed, Marks, Other Requirements, Limit, Skill used, Attribute used, Defense roll/threshold, a very brief description of what the action does, and a page reference. Or better, let the player make it. Just compiling this list helps a lot to get a better grasp of your options.
Protip: Use separate columns for alternative uses/forms of certain actions and for "hidden" actions, like tests to restore functionalities etc. If you use houserules (tweaks to existing actions or made up additional actions), highlight them.
