As a first thing that I can think of is classic scenario when I'm used to shortcut `Ctrl + w` in terminal, which delete last word before my cursor, in any browser this shortcut means `close actual tab`, which is impossible to prevent. Feature Keyboard Lock is solution.
Next thing could be all sort of shortcuts like you said "Ctrl-Alt-Del" and "Alt + F4", im going to try them on some Windows as soon as i get some in my hands in following days. -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
