If you are a keyboard shortcut junkie, here's one for you. On the Mac, you can access the Dock using the keyboard using Control + F3. When you do this, the focus will be given to the Dock (usually to the icon that was last accessed in the Dock). You can then use the Up and Down arrow keys to move between icons in the Dock. You can use the Right arrow when on an icon to show the menu that would have been shown if you Control + Click on an icon in the Dock. You can hit Enter to select any given icon as if it was clicked on. If you want to leave the Dock, just hit Escape.
