Editing Keyboard terminology (section)

==Keys and keycaps==
A computer keyboard is an arrangement of buttons called '''keys'''. The visible part of a key is called a '''[[keycap]]''' or '''keytop'''. Keycaps are normally marked with '''[[legend]]s''': writing that indicates what the key does, such as "Q" or "[[Caps Lock]]".

Various methods exist to put the legends on keycaps. '''[[Double-shot moulding]]''' involves moulding the text out of plastic and then moulding the key around that first moulding, while '''[[pad printing]]''' uses thick, opaque ink to print the text onto the keycaps via a silicone pad. See [[keycap printing]] for a description of these and other methods such as dye-sublimation printing and laser marking.

Keycaps are removable; they are either a friction fit, or clip in place. Below each keycap is a '''keyswitch''', or '''switch''' for short. A keyswitch is an electric or electronic device that detects that a key has been pressed.
