I'm in a technical support role. There are a lot of instances where I need to type the same thing multiple times throughout the course of a day. From responses to customers, to internal forms and documentation. When I notice I continue to have to type something over and over, I can quickly create an entry in TextExpander with a couple of clicks in a matter of seconds. From that point on, I have an easy way to generate the text I need with a few simple keystrokes. TextExpander has at this point has probably saved me hundreds of hours and makes me much more efficient at my job.
