Apple's new Force Touch Trackpad comes with Force Click.

Force Click is a convenient way to invoke secondary actions with what is, in essence, a secondary, "deeper" press into the trackpad. Apple currently ties Force Click into the Quick Look, Look Up, data detector, and detail view functions, as well as a few extras. That means you can generally go deeper just by — wait for it — going deeper. Here are all the basics!

Note: Force Click is currently available on the 2015 MacBook and 2015 MacBooks Pro, and the new Magic Trackpad 2.

Apple is also using the pressure sensitive aspects of Force Click to let you accelerate fast forward and rewind in QuickTime and iMovie, and zoom in maps. The company is using the Taptic engine to hint when you're getting to the end of a clip in iMovie and to rotating back to zero degrees in Photos. It's safe to say we're at the very beginning of Force Click, and that there's a lot more to come!
