I use the option key all the time to jump from one word to another or to delete a whole word as I’m typing and it’s stopped working, pretty much, for this specific use. It still works for keyboard shortcuts just not for jumping over words as I type.
I’m not sure if it has to do with the Monterey update?
Interestingly, I can use it as expected in Chrome, but it doesn’t work in Alfred or Mail or Safari. Is anyone else experiencing this? Either way, any ideas for how to troubleshoot?
