screen - move cursor to beginning of line
In bash I can usually move the cursor to the beginning of the line using CTRL+a.
In screen, CTRL+a is being used for the special screen-commands.
How can I a) use another key-combination for the screen-commands or b) use another combination to move the cursor to the beginning of the line?
To send a Ctrl-A to your application, i.e. bash, from within screen, type
Ctrl-A a
