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.
