Recent updates causing PowerBook fan activity -- Apple's Battery Update 1.1, perhaps in conjunction with Mac OS X 10.3.2, seems to have caused increased fan activity on some PowerBooks and iBooks. Is it a glitch, or a way to cool down those hot aluminum PowerBooks? (11 messages)
Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
