I was stuck in Geany in fullscreen mode and unable to get out. All the suggestions I found on websites were too complicated (for me). I finally discovered that by depressing the ALT key and the V key, the view menu opens and I was able to uncheck fullscreen mode. Problem solved.
This appears to be the way one sees menus while in fullscreen mode: ALT + , e.g., File Edit View etc.
Pressing Keys F11 toggles Geany full screen mode.

What I did to exit command line full screen was :
And I got the normal screen again.
For me it was Ctrl+F but it had to be the right Ctrl button.
