i am trying to make a gemwin in fullscreen without any bar or GEM bar showing at the top
of hte gemwin. but whenever i make it fullscreen, i can't quit fullscreen in case i need to see other windows again.
i have heard that there is some message i can put on top of toggle of fullscreen, using some keyboard setting , say, pressing "esc" on keyboard while seeing fullscreen gemwin i can always get back to see all other windows.
does anyone know the details on how to do it? appreciate it if anyone can help!
