ON KEY LABEL commands are placed on the stack with PUSH KEY.  This
command, when used with the PUSH KEY command, lets you save a set of ON
KEY LABEL commands, make changes to the commands and then restore the
commands.

        Including the ALL keyword with POP KEY clears all current ON KEY LABEL
commands, and clears all ON KEY LABEL commands from the stack.
