They are here: [0]. There is a note at the end of the page which is quite
important. The Gambas IDE is the single definitive reference if you really
want to have an overview of all (or some) of the prefixes for graphical
controls. I tend to forget these prefixes regularly and use slightly
different ones (whatever sounds right). I guess nobody is expected to dive
into the IDE to look up the correct prefix for a control :-)
