Block keyboard in break mode

[MohiuddinSumon]

All keyboard switch should be blocked in full screen mode

when a full screen break is on user should not have access to keyboard shortcut like tab/ ctrl+tab/ windows etc.

Can possibly take a look into ways to make it harder during strict mode, though this will be a lower priority issue as this would be irritating to support across multiple operating systems and could cause major issues if it bugs out.
