Description of problem: It has happened to me too many times that I have locked the terminal by mistake - eg while using emacs inside a screen session. Actual results: It is too easy to press ^ax or ^a^x. Expected results: Would be better if lockscreen was bound to ^aX. Additional info: Also in the current screenrc file, some of the binding are repeated. Is that intentional?
The shortcut is changed to ^aX. The bindings are repeated because the example user screenrc is cat'd at the end of the /etc/screenrc file, but why is beyond me. I will check it out and eventually merge useful changes into real /etc/screenrc and get rid of the cat.
