Apple products can well be compared to natural mines, where one has to dig deep to find diamonds and other valuables. The more you dig, the better diamonds will you get. The case in point here is Mac, which is a designer's delight; the system is widely used by developers and other professionals though.
So where is the diamond here? You can use your three fingers on Mac trackpad and create a drag gesture on Mac running on Mac X El Capitan. This feature can be helpful when your mouse fails to work properly due to some technical glitch or battery life issue. With this finger drag gesture, you can click and drag windows and other applications/icons on your Mac.
Earlier this feature was found in Trackpad settings of System Preferences; but in the latest versions of Yosemite and El Capitan, you can find this feature in the deeper labyrinths of Mac, and therefore, you need to follow a few steps to use this awesome feature. This one is not as easy as you could have done by firmly pressing on keyboard in your iPhone 6s.
