;;; This section adds definitions 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.
