Keyboard quits working

This is similar to a post in 2020 September by @rbanks88
my usb keyboard mysteriously quits working. i might be hitting some f key out by delete while typing because I tend to rush and need to delete characters. I could be hitting = and F10 for instance, or delete plus F11 or F12. when i unplug the keyboard and plug it back in it works again.

Does anyone know hotkeys that work to disable keyboard in catalina? I don’ t have anything exotic running, no automation.

Imac 2017 intel i7 32GB Ram.
Catalina 10.15.7

thank you

Surely you can’t disable a keyboard accidentally. Have you tried a different USB port? Do you have another keyboard you could test?
