The spacebar might be the most used button on your keyboard, but that doesn't mean that it can't do even more. At least, that's what Synaptics thinks. The company — best known for its laptop trackpads — wants to make your spacebar touch sensitive.
That means that you may soon have two different ways to click on your spacebar. You'll still have that satisfying, traditional physical click for typing, but if your laptop or desktop keyboard has the "SmartBar," you can set custom actions for when you merely tap on the spacebar. In fact, Synaptics says you can set five different actions for when you tap on the SmartBar, presumably depending on where you tap the bar.
Perhaps more useful is a feature that lets you highlight the word directly before or after your cursor with a single swipe of the bar, to the left or right, respectively. (If you don't do a lot of typing, the old school way of doing this is control-shift-arrow, or option-shift-arrow on a Mac.) Another gesture that sounds decidedly less useful lets you pinch-to-zoom with your two thumbs across the spacebar.
