POLYKEY=key (or ^key)
Examples: POLYKEY=^W (Control W)
POLYKEY=| (vertical bar)
This parameter only applies to A-Shell/UNIX when PolyShell is in use. (PolyShell is a multi-tasking shell specifically designed for use with A-Shell which allows users to hot key between multiple A-Shell sessions on a single terminal. The specified key may be used at any time to send the current instance of A-Shell into the background and then to either switch to another instance of A-Shell or to the PolyShell menu (depending on whether PolyShell was launched with the –x switch). This key is “hot”, meaning it is always active, except when you have shelled out via the HOST.LIT command or HOSTEX.SBR routine. Also see SWAPKEY.
