For all those that are lazy with their typing, including me, Smiles have finally bought out TextExpander 5 for Yosemite
To be honest, this is the 2nd App I always install, the 1st being Dropbox for the Snippet Syncing, but now it has iCloud Sync, it will be the 1st App installed . . .
Been a while coming but its finally here with some great added features . . . . $44 for the full App or $19.95 for the upgrade from .v4.x.x

New in Version 5:

  1. Suggests snippets from phrases you habitually type
  2. Reminds you of missed opportunities to use your abbreviations
  3. Customise snippet file location
  4. Sync via iCloud Drive or any sync folder
  5. Simplified expansion of lengthy fill-ins and scripts
  6. Search and expand snippets, abbreviations, and suggestions inline as you type
  7. Preview expanded snippet
  8. Refreshed statistics display
  9. Supports JavaScript snippets that also operate on iOS
