Please add more common hotkeys

Hi,

Please add more common hotkeys:

• Ctrl+Alt+Fx
• Alt+PrintScreen+letter
• Ctrl+Alt+backspace

These are usually needed when KVM is connected to Linux machine

Thanks

Ctrl+Alt+Backspace is easily added to the VirtualKeyboard, the others are modifiers and another key, which is not how the virtual key shortcuts work.

I will make a PR for at least that one.

The others you mention would be best served by the soon-to-be-released Macro keys (in Settings)
