Hi Welcome to Emacs Rocks!

I just started using Emacs. I've been using TextMate for a few years and

I've been looking for something else. I tried vim, it's nice.

But I've been using Emacs for a few weeks now and

I'm really loving it, it's awesome. So I was thinking,

Hey! All this cool stuff I have to share with someone - and that's you!

So this is the first episode. If you want to see more, there's a

just follow me @emacsrocks on Twitter. Ok, First trick

I've been doing some Javascript testing lately and every so often I get to these situations

I have some local variables and I want to extract them into the setup method

So let's do that

so the mark is now at the beginning of the first var

the mark and the point of the cursor, together they form a region

including the three vars and the space afterwards.

So let me do: Control-x rectangle text

Which will replace the contents of the region with whatever I write.

That rocks!

That was the first episode, thanks for watching
