I'm using my iMac more and more. The challenge is shifting from a Windows based keyboard over to the iMac keyboard. Windows-based keyboards have a home and backspace key. Here are a few shortcuts I've started to use more and more. Keyboard Shortcuts Shift-delete: Backspace Fn-arrow down: page down Fn-arrow up: page up Fn-arrow left: top of page Fn-arrow-right: bottom of page Spacebar: page down Shift-spacebar: page up Command-spacebar: Open search Teach me! You may know more so post them in this thread.
