Browsing Through a Virtual Form

To allow the user to use the cursor pad keys to view and scroll through the virtual form (i.e., the underlying buffer for the virtual form), use wn_browse() and pass the pointer to the form window dfmp->wnp:

wn_browse(dfmp->wnp);

This call could be used in an event function to allow the user to scroll through the virtual form. You should read more about windows and wn_browse() for details on how browsing works.
