WWDC isn't all about iPhone apps. Long before the iPhone was a twinkle in Steve's eye, WWDC was all about developing for the Macintosh. I had a chance to sit down with the guys behind QuicKeys, a venerable Mac app that will save you a lot of time on repetitive typing tasks. I got a look at the beta, but the full version is now available for $59.95 ($29.95 if you are upgrading from version 3).
For example, if you are constantly typing your email signature, QuicKeys can auto-complete the typing when you type "szm" or any other character combo you like (in a similar fashion to TextExpander). QuicKeys can also create keyboard shortcuts for darn near anything, and record actions for later use. That's really just the tip of the iceberg. QuicKeys has MIDI triggers, a powerful search tool, web actions, an online repository for shortcuts and tutorials, and the company is set to release a QuicKeys remote app for the iPhone/iPod touch (so yeah, you just can't escape that little platform).
Luckily, you can try QuicKeys yourself and get a feel for how powerful it truly is. There's a 30-day trial mode, but Startly (makers of QuicKeys) has a generous "unlimited" trial period, which extends the trial app indefinitely. I know I've often downloaded an app, installed it, then come back close to 30 days later to realize I can't dig into it within the timeout period. Give it a try and I think you'll be pleasantly surprised. If you are a power user, this thing is a lifesaver. If you're a casual user, there's still benefit to typing less throughout the day.
