I have a PowerBook that I hook (in clamshell mode) to a 23" ACD at home and I use a Bluetooth mouse. To save battery in class, I turn off bluetooth since I just use the trackpad. Then, when I get home, it's a hassle to have to open up the laptop after it's plugged into monitor, firewire, usb, and everything to then have to pull it out and try to navigate up to the menu to turn bluetooth back on. Can I set up a hot-key to turn bluettoth on, or toggle it on/off? Thanks!
