TextExpander can be as simple or as geeky as you want. Whatever your level of experience, there’s a TextExpander tip for you:
Make a snippet for your email address. You’ll be amazed at the keystrokes you’ll save not having to type that over and over.
Add one of the Predefined Groups, like HTML/CSS snippets or instant URL shorteners. There’s even an AutoCorrect group to fix your typos.
Try fill-in snippets, which have multiple variable fields. For example, you could have a form letter with blanks for name, product, company, etc. Type your abbreviation, fill in the fields and you’re done.
Create your own AppleScript and shell script snippets.
