When you remember where the buttons are they’re fine to navigate. The average keyboard that meant people can type on without looking has less physical feedback (2 small bumps on f and h).
Yeah, once you get used to typing on a keyboard you don’t really need anything else. I got blank caps for my keyboard because I thought it looked neater. Memorising a row of climate options isn’t that bad. If you mix buttons and dials it’s even easier. If the manufacturer thinks of accessibility they’ll also add tactile bumps and such and make it accessible for people who don’t have great vision too.
Lol as someone who touch types but sometimes has to look down for F-key locations and which symbols are attached to which numbers, this would drive me mad.
F keys are in groups. It’s easy to see which is which workout text.
Symbols are in the category of layout learning.
I had a blank keyboard once. This was so long ago that it was probably a manufacturing fluke but I really liked it. Though whatever the caps say didn’t really affect the use in any way.
