Have you ever tried adding up the number of keystrokes you tap out in a day? We didn’t think so. But we bet you’d be shocked by the total. We were happily surprised when we saw how many keystrokes we’d saved—4,572—after a few days using TextExpander, SmileOnMyMac’s supersmart text-substitution utility. Speed typists might be skeptical about the app’s usefulness—and we might have sided with those skeptics before we installed it. In mere minutes, we created a couple dozen “snippets,” or chunks of text that appear in any application when you type certain shortcuts. TextExpander also allows you to limit the apps that certain snippets work for, which is useful for keeping your html snippets out of Word documents, for example.
