pastie

/pay'stee/ An adhesive label designed to be attached to a key

on a keyboard to indicate some non-standard character which

can be accessed through that key. Pasties are likely to be

used in APL environments, where almost every key is associated

with a special character. A pastie on the R key, for example,

might remind the user that it is used to generate the rho

character. The term properly refers to nipple-concealing

devices formerly worn by strippers in concession to

indecent-exposure laws; compare tits on a keyboard.
