This drives many people crazy, especially since I do this most of the time without reading printed software manuals. Now I'm going to tell you one of the ways I learn software so quickly. I use the menu bar. Most pieces of software have a menu bar. Before I continue, I must tell you to make sure you do any experimentation on a new document or one that you are using for experimentation.

When you click on a menu bar option, more options pop out from the option that you selected. By clicking on all of the major headings, you can see just about all of the features available in the software. If your application has a status bar on the bottom of the window, then here's a great tip that may work for you. It's quite simple - to choose between master menu bar options, use the left and right arrow keys. To choose between options in the menus that pop up from the main menu bar, use the up and down arrow keys.
