Dashboard is now accessible from the F4 key.
Additionally, the Exposé key is now F3 and has expanded functions:
- Pressing the Exposé key - Exposé (all windows)
- Pressing Ctrl+Exposé key - Exposé (application windows)
- Pressing Cmd+Exposé key - Exposé (desktop)
The Command key is now labeled "command."
To access the F keys as function keys (F1-F12), the keyboard now includes the Function modifier key (Fn). Press and hold this key while pressing a function key, F1 through F12, to use it as function key. F5 and F6 are exceptions; they are not dual-purpose keys and do not require the function key.
Note that the Eject key is now directly over the delete key.
