GarageBand was updated with QWERTY keyboard support. This allows you to use keyboard shortcuts!
What's new in GarageBand v2.3.7:• Supports keyboard commands when using a Smart Keyboard or Bluetooth keyboard
• Adds the Wah stompbox pedal and Face Control to Smart Guitar
• Provides stability improvements and bug fixes
I'm sure Apple would prefer that you use this feature with their $200 keyfolio, or at least an Apple keyboard, but Studio Live Today's Pete Johns shows off the shortcuts working on an old Microsoft keyboard!
