Question:switch between viewer and browser

[kesdoputr]

Is there is a switch to change Browser(fullscreen) <> Viewer(fullscreen)?
If use Xnview filename.jpg(example),it will open a viwemode only,i can use -full to let it fullscreen at start.
But i need a switch that when i press enter can change to browser mode,then when press enter again will change to viewer mode with fullscreen,but now Xnview seems don't have the option?
Now Xnview have only Browser>Fullscreen>Viewer,Browser>Viewer>Fullscreen or Browser<>Viewer,could your add one switch Browser(fullscreen)<>Viewer(fullscreen)?

Thank you for reading to here
