101 key exended keyboard
Hello, I know this isn't a Keyboard Maestro question, per se, but I figured if there is a community that is likely to know one end of a keyboard from the other, it's probably this one!
A whole bunch of my keys have all stopped working at the same time, namely the ⇪, ⇥ , ` and esc keys. I'm not aware of any physical damage or spillage which may have occurred, but the fact that I was able to replace the keyboard with another where the corresponding keys are working, makes me lean towards some sort of hardware failure being the cause.
Googling revealed a few people who had had similar problems with the same set of keys, so I'm not 100% convinced it isn't an OS problem, though. I tried to carry out an SMC reset as per this page https://support.apple.com/en-gb/HT201295, but I'm not sure if it worked - there was no reassuring message saying "SMC reset worked - Happy Days!".
Thoughts, anyone?
