In the GNU screen application, the bind key C^a that is used in bash, doesn't work anymore, because C^a is the bind key that screen uses for his commands. Is there any other bind key for bash that puts the cursor at the beginning of the line?


Thanks,

Yes, you can define whatever keys you want, both in bash and screen. Bash uses the readline library for input, which gets it's key bindings from ~/.inputrc or /etc/inputrc (see the READLINE section in the bash man page for syntax).

However, you might prefer to change the binding for screen. Personally, I use ^W which is unused in all my other apps. You can try this on the command line with -e^Ww (that is, ^W is the escape key, and you press w again to pass a literal 'w' through to the app). You can set this permanently in your ~/.screenrc with 'esacpe ^Ww' or whatever key you want. See the screen man page for more details.
