This fantastic piece of software allows you to define custom abbreviations that expand to your frequently used phrases, long paragraphs, and more!  Here is an example: a client asks me to email a description of how my custom Daylite report design process works.  I have a few standard paragraphs that describe the design process, procedures, pricing, and turnaround time.  I could type it all out every time, or keep a text document that I can copy and paste from, but wow that is a ton of unnecessary work since I get multiple requests for that info every day.

A better way:  use TextExpander.  I defined a snippet in TextExpander so that all I type is reportpricing and the many paragraphs that describe my design process fill right in.

TextExpander is also great for small snippets, especially in your Daylite database. Some of my other snippets include:
typing fu [no pun intended] expands to: follow up
typing rc expands to: return call
typing dt expands to: the current date and time
