True story: upon playing my first computer FPS, I thought that the default WASD movement keys were a mistake so I switched changed them to the arrows. Turns out, I'm an idiot.
I fixed the missing keys by soldering some copper wires to the curcuit board where the keys were, so when I touch the wires toghether, it has the same effect as pressing the keys.

User foxhead128 has a habit of Alt+Tabbing a lot, so their Tab key wore out pretty quickly. Nothing a bit of Scotch tape couldn't fix.
Hey, it worked for Skyrim!
