Trial and error, and a bit of luck.
Having a private page to work on means that you can experiment with ideas without anyone knowing. If in doubt right-clicking usually comes up with a menu or possibly solution whether you are in Voice or Microsoft Word.

An online manual of functions and functionality would certainly not go amiss.
