Startup keyboard shortcuts Mac OS X Lion
Here are the modifier key symbols you can see in Mac OS X menus:
(Command key) - On some Apple keyboards, this key also has an Apple logo ()
^ (Control key)
(Option key) - "Alt" may also appear on this key
(Shift key)
(Caps Lock) - Toggles Caps Lock on or off
fn (Function key)
Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until "Safe Boot" appears). Tip: If a startup function doesn't work and you use a third-party keyboard, connect an Apple keyboard and try again.
