+;;; 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.
