You’re right, and I wasn’t very clear with my comment which is unfortunate. I never meant to imply that any of those things were
impossible with fn-keys, just that they weren’t very discoverable. The Touch Bar shows me what features are available at any given time, fn-keys don’t. Sure I could go hunting for the relevant docs, maybe I’d even learn a few key combinations along the way, but my experience tells me I won’t. Other people might, but I never much cared for the fn-keys for this very reason – I never knew quite what they did in what contexts, and didn’t care enough to find out.
So for me, the Touch Bar makes these contextual commands discoverable, and that’s worth more than the tactility of physical keys. Doesn’t matter if I can touch without looking, if I don’t know what the keys do. Besides, after a couple of years with the Touch Bar I feel like muscle memory seems to work about the same anyway, I never have to look for the mute button in Zoom for instance, I know where it is.
Thanks for challenging my comment, prompting me to (hopefully) clarify!
