86    ** New command `display-local-help' displays any local help at point
87    in the echo area.  It is bound to `C-h .'.  It normally displays the
88    same string that would be displayed on mouse-over using the
89    `help-echo' property, but, in certain cases, it can display a more
90    keyboard oriented alternative.
91    
92    ** New user option `help-at-pt-display-when-idle' allows to
93    automatically show the help provided by `display-local-help' on
94    point-over, after suitable idle time.  The amount of idle time is
95    determined by the user option `help-at-pt-timer-delay' and defaults
96    to one second.  This feature is turned off by default.
97    
98    ** New commands `scan-buf-next-region' and `scan-buf-previous-region'
99    move to the start of the next (previous, respectively) region with
100    non-nil help-echo property and display any help found there in the
101    echo area, using `display-local-help'.
