On: Run last command as root

If you use bash, read the "Command Line Editing" section of "info readline".

[telemachos → jrockway]

You can also tweak the behavior of readline (for Bash and other applications) and custom make your own key combinations by editing your ~/.inputrc file. A random example from mine:

    # Insert double quotes & set cursor between them
    "\C-x\"": "\"\"\eb"
    #
    # Insert single quotes & set cursor between them
    "\C-x'": "''\eb"
