In bash I can hit Ctrl +  a and go to first of the command line. But in screen Ctrl +  a does not do this. How do I go to first of command line in screen?
How do I go to beginning of command line when I am inside the screen?
keyboard shortcuts;gnu screen
You can press Ctrl+a followed by a to go to the beginning of the line. The a sends a Ctrl+a to the terminal.
