Run last command as root

This ends up annoying me on a regular basis. Let's say I want to make a directory and then go to it. I would type:

  mkdir foo<Ctrl-p><Ctrl-a><Alt-d>cd<Enter>

Except when using screen, <Ctrl-a><Alt-d> (really just <Ctrl-a>d) detaches the session. It's solved easily enough ("screen -r"), but it always yanks me out of my groove.

Put something like this in your .screenrc:

   escape "^^^^"

That will set the escape character to ctrl-carat instead of ctrl-a. To type a literal ctrl-carat, type it twice.

This is the same as:

   screen -e ^^^^

I prefer to bind it to ` with `` to send a real `. It makes it really easy to flip back and forth between two screen windows since last-window is now:

`q

Now I don't even have to use Ctrl. This takes a little getting used to, but I prefer to use $() instead of `` for shell scripts (I use bash/zsh) so I don't make use of ` that often.

I do have bindings on F11 and F12 to toggle the escape character between ` and C-o. (Just in case I need to paste something into a terminal with ` characters.)

(Note: This whole setup is ripped off from some StackOverflow or HN post.)
