And under Keyboard -> Keyboard Shortcuts make sure Full Keyboard Access is on 'All Controls' so you can focus/select buttons with tab.
Also, make that useless Caps Lock key into Ctrl :)
Ctrl+F2 = Access Menu bar Ctrl+F3 = Access Dock
I will give someone 1 american dollar if they can tell me how to get menu bar selections to wrap back around to the top when I get to the bottom of the menu.
EDIT - the magic mouse has been fantastic for eliminating the need for precise clicking when scrolling - that swipe to scroll feature is amazing, especially in tabular apps like Sequel Pro and Excel.
