At first, I thought the new MacBook Pro touch bar was actively worse than a traditional keyboard for adjusting volume or brightness. After all, with keys you can turn the volume up or down with a quick tap. From what I saw of the touch bar you needed to tap the volume button, then adjust the slider that appears. A tap, followed by a tap-and-move motion.
I was wrong. There’s a gesture that lets you adjust volume or brightness in one quick motion, though it’s hard to stumble upon if you don’t know it’s there. Just tap and hold either function in the Control Strip , then move your hand to the left or the right. The level will adjust, without you ever lifting your finger.
It’s a little weird at first,…
