Every now and then some key combination clears my working (Gnu) screen and brings up this message:

Screen used by <username> on host01
Password:

What key combination causes this and what does it signify?

According to this source it's the key combination Ctrl+a and then x.

It signifies locking the screen and unlocking it with your password.

@vfclists, if you find this disruptive, you can add bind x to ~/.screenrc so that key combination will no longer work. –  Arcege Jul 6 at 0:16
