How to fix my up and down arrow keys, they no longer work.
My up and down arrows still can be pressed but nothing happens and they feel a bit thick. Feels almost like something is under the button blocking contact. Please help!! thanks!

There probably is something there. Blocking the keys from being pressed. It could be crumbs, so shake the computer up and down, sideways, and upside down. Or it could be some sticky fluid, that's harder to clean, try a warm wet towel.
