I've been using, and enjoying, a Microsoft Sculpt Wireless keyboard for the past couple years. All of a sudden tonight the backspace key stopped working. Using the keyboard viewer, I can tell all the other keys are fine:
What's odd is if I disconnect and reconnect the USB receiver the viewer shows the backspace key like it's stuck. It's not. I've read some of the other answers on here about checking for crumbs and dust. Blown it out with air but haven't gone as far as disassembling it.
2013 iMac running 10.11.6 but it's also sadly happening on my MacBook Pro running the latest version of High Sierra. Love this keyboard, but wanted to see if anyone else has solved this without popping keys off.
I'm considering treating this as a challenge to improve my typing and spelling :)
