function.")

line to bottom of window.  Repeated presses then scroll up or down a

;; up properly, however.  If you do a {M-x load-file hypb.elc RET} and then
;; hit {C-x C-e} after the closing paren of the following function,
;; (hypb:domain-name), you will see whether or not yours is configured
;; properly.  If it is not, uncomment the following line and set it to the
