title: Ruby-mode in Emacs in short-cut key for compile/run?
body: <p>I know a little bit about Emacs as I used it to write my thesis in AUCTex.</p>
  
  <p>However, this time when trying to write some simple ruby program mostly to learn, I googled around for Ruby in Emacs and couldn't found what I am looking for. </p>
  
  <p>Based on what I read so far, I know that the Emacs(23.3.5) I am using has in-build ruby-mode, which should support basically syntax highlighting, auto indenting etc. But how about short-cut key for debug/run, something like <a href="https://github.com/emacsmirror/mode-compile" rel="noreferrer">Mode Compile</a>? </p>
