How to lubricate switches on your keyboard
Beneath each keycap on a keyboard is a switch that registers keystrokes. Tap your space bar, Enter key, and some random keys, and try to notice the differences in sound and feel. Perhaps the space bar makes a lighter thump than the letter keys, or maybe the Esc key is a little scratchy on the way back up. Although lubricating switches isn’t entirely necessary for typing or gaming, doing so can smooth out every keystroke and provide a satisfyingly consistent sound for each key.
