F-key shortcuts for Mac OS X 10.6 Snow Leopard
I’m a huge fan of keyboard shortcuts because reaching for the mouse only slows me down. So, when I find some new (and useful) keyboard shortcuts, I feel compelled to share and here are couple easy ways to access System Preferences without resorting to your Mac’s mouse.
While holding the option key, press the…
• The F3 or F4 key to open System Preferences > Exposé/Spaces
• Mute, Volume Up or Down key to open System Preferences > Sound
Although these Option + f-key shortcuts give you direct access to the Sound and Exposé/Spaces preference pane, you can use to bring up System Preferences and then go to the specific pane you need. That is, as your left hand brings up System Preferences, your right hand can be reaching for the mouse — two motions at once, one hand washing the other, saving time.
