Computer keyboard

Laptop keyboard with its keys (except the space bar) removed, revealing crumbs, pet hair and other detritus to be cleaned away.

In computing, a computer keyboard is a typewriter-style device which uses an arrangement of buttons or keys to act as a mechanical lever or electronic switch.
