Re: Hex Code for Field+ key

["Bob O." <otis_the_cat@xxxxxxxxxxx>]

Unfortunately, web/gui is not an option for this application.  We'll figure 
something out.  We may just have to go against the user "wishes" and make 
them use a function key to page through the different record formats for the 
display instead of using the enter key as they want.  IT Rules!
