;;; This section adds defintions for the emacstool users
;;; emacstool event filter converts function keys to C-x*{c}{lrt}
;;;
;;; for example the Open key (L7) would be encoded as "\C-x*gl"
;;; the control, meta, and shift keys modify the character {lrt}
;;; note that (unshifted) C-l is ",",  C-r is "2", and C-t is "4"
;;;
;;; {c} is [a-j] for LEFT, [a-i] for TOP, [a-o] for RIGHT.
;;; A higher level insists on encoding {h,j,l,n}{r} (the arrow keys)
;;; as ANSI escape sequences.  Use the shell command 
;;; % setkeys noarrows
;;; if you want these to come through for emacstool.
;;;
;;; If you are not using EmacsTool, 
;;; you can also use this by creating a .ttyswrc file to do the conversion.
;;; but it won't include the CONTROL, META, or SHIFT keys!
;;;
;;; Important to define SHIFTed sequence before matching unshifted sequence.
;;; (talk about bletcherous old uppercase terminal conventions!*$#@&%*&#$%)
;;;  this is worse than C-S/C-Q flow control anyday!
;;;  Do *YOU* run in capslock mode?
;;;

;;; Note:  al, el and gl are trapped by EmacsTool, so they never make it here.
