I am inside a screen (screen -Ra). I have a long command, and I am at the end. Instead of keeping the left arrow, how can you go to the beginning of the line?
CTRL-A works when I am in a normal window, but when I am inside a screen pressing CTRL-A gives me a message "No other window" - seems like CTRL-A is dispatched to the screen.
How do you go to the beginning of a line in a screen?
