Select a word and then Force-click (or click with three fingers) to look it up in your Mac's dictionary and thesaurus. You can enable and customize them in System Preferences ➙ Trackpad: Here are some useful built-in gestures you might not have known about. For example, in the Point & Click section, you can enable the Secondary Click gesture by checking its box, and then the dropdown lets you choose if that secondary click will be a two-finger tap or click in a specific corner of the trackpad. Some gestures even have options you can select from a dropdown menu. It's definitely worth a few minutes to watch all the previews and decide which gestures could work for you. As you mouse over or select each gesture, a video preview on the right will show exactly what will happen. There's no mystery to these options, either. It's already packed with gestures you might not be using that can really speed up some tasks on your Mac. If you've got a Mac laptop, you should go to System Preferences and open the Trackpad pane.

If a mouse or trackpad action is taking too long, or somehow hurts your hand - for example, selecting text with a trackpad - there's probably a better, faster, easier way to do it. Even better, with a utility like BetterTouchTool you can customize gestures on your trackpad further, as well as set up a mouse or any other input device you can connect to your Mac.
