PUSH KEY [CLEAR]

-----------------------------------
PUSH KEY places all current ON KEY LABEL commands on a "stack" in
memory.
-----------------------------------

PUSH KEY, when used with POP KEY, lets you save ON KEY LABEL commands,
change these commands and then restore the previous commands.

For example, you could use a different set of ON KEY LABEL commands when
a Browse window is open.  Before you open the Browse window, use PUSH
KEY to save the current ON KEY LABEL commands in memory.  You can then
add or change ON KEY LABEL commands specifically for the Browse window.
After you close the Browse window, your previous ON KEY LABEL commands
can be restored from memory with POP KEY.

ON KEY LABEL commands are placed on and removed from the stack in a
"last in, first out" order.

DISPLAY STATUS and LIST STATUS show the current ON KEY LABEL commands.

Clauses

CLEAR

commands are saved on the stack, and the commands are then cleared.
