+** Simple hooks
+
+Simple hooks are just JavaScript variables that point to particular
+functions that OrgInfo will call. There are two simple hooks thus far:
+=OrgInfoPageInsertFunction= and =OrgInfoAfterNavigateFunction=.
+
+If you assign your own functions to these variables, be sure to do so
+after OrgInfo has loaded, or they will not work. You can do so from an
+org file like this:
+
+#+begin_src org
+ #+begin_export HTML
+ <script type="text/javascript">
+ function MyInsertButtons (pageNumber)
+ {
+   [code goes here]

+ OrgInfoAfterNavigateFunction = MyAfterNavigate;

+#+end_src

+*** OrgInfoPageInsertFunction
+
+The variable =OrgInfoPageInsertFunction= should hold a JavaScript
+function that accepts an integer identifying which OrgInfo section
+header to insert HTML into. The function should return a string
+consisting of HTML to insert into the dynamic page header that OrgInfo
+builds for each section.
+
+*** OrgInfoAfterNavigateFunction
+
+The variable =OrgInfoAfterNavigateFunction= should hold a JavaScript
+function that accepts an integer identifying which OrgInfo section has
+been switched to. The function should do whatever user-defined action
+is desired. Any return value is ignored.
