A decade ago, Apple began switching from trackpads with mechanical clicking mechanisms to Magic Trackpads, where clicks are simulated via haptic feedback (in Apple’s parlance, the Taptic Engine). And, with Magic Trackpads, you can use Force Touch — a hard press — to perform special actions. By default, if “Force Touch and haptic feedback” is enabled on a Mac with a Magic Trackpad, a hard Force Touch press will perform a Look Up — e.g., do it on a word in Safari and you’ll get a popover with the Dictionary app’s definition for that word. It’s a shortcut to the “Look Up in Dictionary” command in the contextual menu, which is also available via the keyboard shortcut Control-Command-D to look up whatever text is currently selected, or that the mouse pointer is currently hovering over — standard features that work in all proper Mac apps.
