Slow down and remember that this is much the same experience as learning how to drive a car. It'll take a while to get easy with it, just keep pushing forward. Yeah right, friendly. Nevertheless, the documentation is your best friend, soldier. It could save your life.
Tutorials are good at introducing the features of a tool peppered with examples.
Tutorials tend to be chatty, spread out and best worked through cover to cover. References with good Tables of Content in the front, useful content with examples as appropriate in the middle, and detailed indexes in the back, are treasures. Unfortunately, a lot of the documentation which comes with computer and software products is incomprehensible techno babble written by people from different planets. Fortunately, there is a thriving market in helpful books written by professional authors in simple language on almost every computer and software product. Next time you are at the neighborhood bookstore, check out the Computer Books section.
