Learn some basic keys

I boostrapped my first emacs config using Vim, I have to admit :-) But
now it's time to learn some basic key combos so I can not be a bumbling
idiot in this thing.

First, let's break the crutch. This is going to be painful...

In my .zshrc:

    export EDITOR="emacs"
    export GIT_EDITOR="emacs"

Then, in the terminal:

    git config --global core.editor emacs

I see http://www.rgrjr.com/emacs/emacs_cheat.html has some handy keys
I'll need:

* C-a / C-e - already knew these from the command line, yay!
* C-x s     - save a buffer
              it seems C-x C-s does the same (not sure why)
* C-s       - search forward
* C-s C-s   - repeat search (took me a bit to figure that one out!)
* C-x C-c   - exit!

So, we're making some progress! This feels akward, but at least I can
use Emacs like I'd use Nano if I'm in a pinch :-)

Copy and paste is still a mystery, but we'll get there!

BTW, I copied the belw yes-or-no thing from Mark Ranallo's config here:

Man, these colors are drab. Gotta fix that soon.

Stay tuned!
