(defvar hkey-always-display-menu nil
  "*Non-nil means always display the Smart Menu window when the Action or Assist Key is pressed and the Smart Menu system has been loaded.
If a Smart Menu is already displayed, perform another Action or Assist Key
function.")

(defvar smart-scroll-proportional t
  "*Non-nil means Smart Keys should scroll relative to current line when pressed at the end of a line.
Action Key moves current line to top of window.  Assist Key moves current
line to bottom of window.  Repeated presses then scroll up or down a
windowful.  Nil value instead ignores current line and always scrolls up or
down a windowful.")

;; hit {C-x C-e} after the closing paren of the following function,
