Over at Chris Breen’s Mac 911 Tips & Troubleshooting there’s a short sweet entry about using the Option key and the F keys for System Preference Shortcuts.
Just the other day I was fumbling round (in front of a bunch of Windows users no less) opening my System Prefs to adjust my display after hooking it to a (very crummy) projector. Option F1 would have been much niftier.
And in fact, now I look at my keyboard more closely I see the F7 key has what might be an icon for mirroring monitors, which could have been even easier. And a search of the Help finds:
By default, your PowerBook starts up in dual-display mode. Press the F7 key to switch between dual-display and video-mirroring modes.
To detect the TV or other external device, hold down the Command key and press the F2 key.
Oh, and that crummy projector …. I have some photos which look spectacular on my gorgeous screen — beautiful colours and lighting (all thanks to my Canon Digital Rebel). We were having a “show and tell” at the final night of the photography class I’ve been attending. I hooked my Powerbook into the school’s projector, organised the displays and yuck. Gentle brick red became garish orange, soft light became harsh, colours went all over the place. Sigh.
