Scroll Gesture is nothing but, when you scroll over any icon on your Mac’s dock, it will reveal all the currently opened windows on the screen. This is a simple gesture, which lets you quickly switch between multiple windows of any application without using the keyboard shortcuts. This will be very helpful for people who use Trackpad a lot. To enable this gesture, you don’t need to download or install any app, all you have to do is, just type a simple one line command on your terminal. Here’s how to do it.
Step 1: To open the Terminal on your Mac, hit “Ctrl + Spacebar” on your keyboard. This will open Spotlight search on the desktop. Now type “Terminal” in the search box. Choose the “Terminal” option in that list as shown in the screenshot below.Step 2: Now copy the command shown below and paste it into the Terminal window.
defaults write com.apple.dock scroll-to-open -bool TRUE; killall DockStep 3: That’s it, now you can swipe over any application on your dock to reveal the windows. If it didn’t work at first, try restarting your computer.
Step 4: If you feel like, it is not much useful and want to remove it from your dock, again open your Terminal window and copy, paste the command shown below.
