Completing a word!
A great tip submitted by Frank Boer: Completing a word! When you're typing in a text editing application such as Pages or TextEdit, it is possible to get a pop-up with all the possible words that you might writing. So if you are in the middle of writing a complex word, instead of checking it out in the dictionary or writing it wrong and correcting it with the spell-check feature, you can easily use that feature by hitting "Esc". A drop-down box will pop-up. You can simply highlight the correct word with the arrows and hit "Tab" to keep it. Thanks for the great tip Frank!
