;; BUTTON-FUNCTIONS are the function names to call, in order, to create

+;; Another tweekable variable is `speedbar-stealthy-function-list'

+;; name matching `speedbar-add-expansion-list'. (It does not need to
+;; exist.). This provides additional display info which might be
+;; time-consuming to calculate.
+;; Lastly, `speedbar-mode-functions-list' allows you to set special

+;; over ridable, but more will be added as the need is discovered.
