Operating a mouse or trackpad is super easy, but behind their simple exteriors these intuitive input devices hide a whole host of shortcuts and extra features that aren't immediately obvious - and if you don't already know about them, you're missing out. Here are our favourites.

Windows (On a Mac): If you're running Windows on your killer Mac hardware, then you've probably noticed that the trackpad isn't quite as smooth and feature-filled as it is in OS X. Trackpad++ Brings more gestures, better scrolling, and lots more to Mac trackpads in Windows 7.

You might be one of those people who find the old mouse and keyboard standbys inadequate. Quaint, even! Maybe you embrace touch as the future of computer interfaces. You might envy the Magic Trackpad, but lack a mac. Envy not!

A laptop that's hard to type or point with isn't much of a help when you're getting things done away from your desk. But you can fix and replace your keys and touchpad rather than take a big credit card hit.
