;==========================================================
; Control key bindings for NTS 1.0
;   - All command keys must be control chars
;   - The length of the list must not be changed.
;   - The order of the list must not be changed.
; Normal commands are control chars ^A .. ^^ and 1fh for DEL
; There are four meta-keys which access commands coded to them.
;   - Meta-key #1  ^n + 80h + 0
;   - Meta-key #2  ^n + 80h + 20h
;   - Meta-key #3  ^n + 80h + 40h
;   - Meta-key #4  ^n + 80h + 60h
; Disabled keys use '-'


; Shift factors for meta-keys

k0	equ	0		; Control key
k1	equ	80h		; Meta 1
k2	equ	80h + 20h	; Meta 2
k3	equ	80h + 40h	; Meta 3
k4	equ	80h + 60h	; Meta 4

; Generate control key from char and shift factor

key	 macro	x,m
	db	x-'@'+m
	 endm
