Hello, I usually have 2 firefox windows open on my new MBpro core2duo. I can easily keystroke through the various tabs in the windows but when i want to switch to the other window I usually hit Fn F10 to show all firefox windows then i have to drag my mouse and click on it. is there a key command for toggling between the f10 windows???? I can cmd tab through the open programs but it's not the same obviously. Also, it's embarrassing as hell when you start up your macbook in 100 person medical school lecture hall and the startup noise goes off. I try to mute my volume before shutting it down but is there a keystroke to override the noise on startup? T, good with PCs, still awful with macs but in love with this laptop.
