TextExpander is a program that aims to save you time by auto-replacing snippets of text with the content of your choice, or to quote their Web site: "Save yourself time and effort by typing short abbreviations for frequently-used text and images."
So for instance when you type ,h1 it will change it to <h1></h1> with the cursor placed between the ><.
After some searching I have yet to find a resource/forum-thread/whatnot that discuss the uses of this marvelous program.
I am therefore looking for your best snippets or a link to a resource where I can find this.
Oh and one thing I can think of right away is sigw, sigp for my work/personal email signature.
