Exiting from Fullscreen Mode in VNCViewer
Before you enter Fullscreen mode, if you right-click the blue title bar and select 'Options'...
Click on Inputs and down at the bottom it says 'Menu key:'. Select F8 there. You can also select any other function key.
Then, go back to Display tab and pick Full Screen Mode.
To exit from full screen mode press F8 and uncheck 'Fullscreen'.
CTRL-ALT-SHIFT-F is not one of the choices. Maybe some old version of VNCViewer allowed that. Mine is VNC Viewer 5.2.3 (r8648) 32-bit Jan 28 2015
