Write repetitive emails quickly with Texter [LifeHacker]

I've used this program quite a bit when I was responding to customer service inquiries and writing the same thing over and over again. It's easy because you can customize it to your liking. I had it setup so that I pressed a letter, then tab, and it will write out a sentence for you.

Very useful, it will work anywhere that you can input text.
