Mar. 11, 2010: It lets you create snippets of frequently used text or images, then instantly paste said snippets into any app simply by typing an abbreviation. It's like a rubber stamp for working on your Mac, and it just got a lot more...stampier--but in a good way.

TextExpander 3 offers a new snippet creation window accessible via a keyboard shortcut, which can save you time while you're creating a snippet that can save you even more time. It also introduces "fill-in snippets," which are basically a 21st century version of your own customizable, powerful Mad Libs. After typing an abbreviation to expand a text snippet, users can proceed to "fill in the blanks" with custom information that doesn't fit into a template. This is great for personalizing e-mail templates on the fly or sending a customer a copy of their receipt.

A new search box lets users quickly find just the right snippet to expand or edit, and one-click sync options in TextExpander's preferences now make it a snap to sync your snippets between Macs via your choice of MobileMe or Dropbox. Of course, the new version also syncs with TextExpander touch for iPhone and iPod touch.

TextExpander 3 also marks the demise of its previous existence as a System Preferences pane; it's now a stand-alone application (requiring Mac OS X 10.6 Snow Leopard) that can hide its Dock icon and live entirely in the menubar. A 30-day demo is available to new users, and a full license costs $35. Owners of previous versions can upgrade for $15, though if you purchased after November 1, 2009, the upgrade is free.
