DESCRIPTION

        Once a form has been posted (displayed), you should funnel
        input events to it through form_driver.  This routine  has
-       two  major input cases; either the input is a form naviga-
-       tion request or it's a  printable  ASCII  character.   The
-       form driver requests are as follows:
+       three major input cases:
+
+       -  The  input  is  a  form navigation request.  Navigation
+          request codes are constants defined in <form.h>,  which
+          are distinct from the key- and character codes returned
+          by wgetch.
+
+       -  The input is a printable character.  Printable  charac-
+          ters  (which  must  be  positive,  less  than  256) are
+          checked according to the program's locale settings.
+
+       -  The input is the KEY_MOUSE special key associated  with
+          an mouse event.
+
+       The form driver requests are as follows:
 
        REQ_NEXT_PAGE
             Move to the next page.

+       If  the  second  argument  is  a  printable character, the
        driver places it in the current position  in  the  current
        field.   If  it is one of the forms requests listed above,
        that request is executed.
 
-       If the second argument is neither printable ASCII nor  one
-       of the above pre-defined form requests, the driver assumes
-       it  is  an  application-specific   command   and   returns
-       E_UNKNOWN_COMMAND.  Application-defined commands should be
-       defined relative to  MAX_COMMAND,  the  maximum  value  of
-       these pre-defined requests.
+   MOUSE HANDLING
+       If the second argument is the KEY_MOUSE special  key,  the
+       associated mouse event is translated into one of the above
+       pre-defined requests.  Currently only clicks in  the  user
+       window  (e.g., inside the form display area or the decora-
+       tion window) are handled.
+
+       If you click above the display region of the form:
+
+              a REQ_PREV_FIELD is generated for a single click,
+
+              a REQ_PREV_PAGE is generated for a double-click and
+
+              a REQ_FIRST_FIELD is generated for a triple-click.
+
+       If you click below the display region of the form:
+
+              a REQ_NEXT_FIELD is generated for a single click,
+
+              a REQ_NEXT_PAGE is generated for a double-click and
+
+              a REQ_LAST_FIELD is generated for a triple-click.
+
+       If you click at an field inside the display  area  of  the
+       form:
+
+              -  the form cursor is positioned to that field.
+
+              -  If  you double-click a field, the form cursor is
+                 positioned to that field  and  E_UNKNOWN_COMMAND
+                 is  returned.   This  return  value makes sense,
+                 because a double click  usually  means  that  an
+                 field-specific action should be returned.  It is
+                 exactly the purpose of this return value to sig-
+                 nal  that an application specific command should
+                 be executed.
+
+              -  If  a  translation  into  a  request  was  done,
+                 form_driver returns the result of this request.
+
+       If  you clicked outside the user window or the mouse event
+       could  not  be  translated  into   a   form   request   an
+       E_REQUEST_DENIED is returned.
+
+   APPLICATION-DEFINED COMMANDS
+       If the second argument is neither printable nor one of the
+       above pre-defined form requests, the driver assumes it  is
+       an application-specific command and returns E_UNKNOWN_COM-
+       MAND.  Application-defined commands should be defined rel-
+       ative  to  MAX_COMMAND,  the  maximum  value of these pre-
+       defined requests.
