I decided to remap the F13 key to do the work of one of the other F Keys I use all the time. F9, F10 and F11 are used for Exposť. F12 activates the Dashboard. (What about F1 through F8? That is a story for another day.) I decided to remap the F13 key to activate the Dashboard since I use Dashboard the most, but using this hint you can remap any of the Exposť F Keys as well.
To remap your F13 key:
- Open System Preferences from the Dock or the Apple Menu.
- Choose the Dashboard and Exposť Preference pane.
- Change Dashboard dropdown from F12 to F13.
- Close System Preferences
