If you (a) own an Intel-based Mac, and (b) have installed Windows on it via Apple’s Boot Camp, then you’re familiar with how you tell your Mac whether to boot into OS X or Windows: just hold down the Option key at startup, then use the arrow keys or mouse to choose the Windows or OS X partition.
But here’s a nify alternative—good for showing off to the neighbors, as well as those situations when you can’t reach the keyboard after choosing to reboot. Make sure you’ve got the Apple Remote in hand, and press and hold the Menu button during startup. Just as if you were at the machine, the boot loader will appear. From here, use the Forward and Backward buttons to cycle between the two operating systems, and activate the desired one by pressing Play.
No muss, no fuss, no keyboard required!
