Arrow keys not working MacBook Air 2017
I had my battery replaced and then I updated my computer to Monterey 12.4. Since then, the arrow keys no longer work. I have checked the keyboard settings and it doesn't show the arrow keys on it (nor the tab, shift. or return), not sure if that's normal or not. If I do hit the arrow key, it puts a blue rectangle around the window that is open and the space bar instead of adding a space, moves back one letter and doesn't work. When I try to click in the area, the cursor doesn't allow me to continue typing. It doesn't matter if I'm using Safari, Pages, Numbers, etc. If I click on a folder, it automatically puts a blue rectangle and then turns the folder dark and I can't access it. This is driving me crazy! I need the use of these keys. Any suggestions aside from restoring it? Thank you
MacBook Air 13″, macOS 12.4
