patch
pastie /pay'stee/ n.
An adhesive-backed 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.
