; CUA-feel macros for MicroEMACS 3.11c
;
; Pierre Perret - April 1992

; Uses mark9 as CUA anchor and mark8 as a temporary (for mark swapping).
; Uses the Clipboard for CUA copy/cut/paste in MS-Windows version (MEWxx),
; uses the kill buffer for same in other implementations.

; NOTE:
; - some key sequences are not supported by MicroEMACS-DOS:
;     Shift+Arrow, Ctrl+Ins/Del and Shift+Ins/Del/Home/End/PageUp/PageDown.
; - Shift+Ctrl+Arrow/Home/End not supported by either MicroEMACS-DOS or MEW10.
;
; To offset that, the special keys have been assigned equivalent function
; keys: Ins=F9, Del=F10, Home=F1, End=F2, PageUp=F3, PageDown=F4,
;       ArrowLeft=F5, ArrowUp=F6, ArrowDown=F7, ArrowRight=F8
; for Shift or Ctrl combinations (using Alt for Shift+Ctrl cases)

; set $hilite 9     ; for future MEW version that will be able to
;                   ; show region9 hilited
