If you’re like me, you don’t particularly care for OSX’s Dock magnification feature. I just don’t like trying to hit a moving target, especially when I’m dragging files to drop on an icon on the Dock! But every once in a while, I do have the desire to have the feature enabled. You can quickly enable Dock magnification, without turning it on in your System Preferences by holding down Control + Shift while hovering your mouse over the Dock. When you release the keys, Dock magnification is turned off.
