> important buttons I use multiple times daily, like those for brightness and volume adjustments, now require the use of two-step touch-and-slide actions instead of my preferred key-mashing. This is configurable. Just go to System Preferences > Keyboard, and on the first tab you can choose whether the touch bar shows (a) app specific controls plus an expandable control strip (the default), (b) the expanded control strip (the old default behavior), (c) function keys, or (d) app specific controls w/o expandable control strip. Options (b) & (c) match the keyboard options without touchbars, and as before you toggle between them with the Fn key. The upside with the touchbar is you can see whether you’re in function or control mode. In any case, sounds like (b) is what you want. Disclaimer: I’m running High Sierra so not sure if this is available on Sierra, but assume it is.
