Arrow keys won't go back on MacBook Air
I have a Macbook M1 2020. I pulled off the right and left arrow off my keyboard to make sure the coffee I spilled did not get under them. (No coffee had gotten underneath.) Then I couldn't get the keys back on. They wouldn't click back onto the plastic mechanism underneath. Then the plastic mechanism came off of one of them and I couldn't get it back on. Then I lost the black top part of one of the keys. Sigh.
Is this fixable? Or am I going to have to live with 2 exposed keys that won't really work?
Thank you for any guidance!
