title: open a file in an emacs buffer while in emacs terminal
body: <p>Suppose I am in terminal in Emacs (M-x term), and I list the following files in current directory:</p>
  
  <p><code>text_code.R</code></p>
  
  <p>Now I am in bash-3.2$ (terminal) and hope to open this .R file in another Emacs buffer and then edit. Is there a way to do it? This might be a trivial question, for I am a newbie to Linux and Emacs. Thanks in advance!</p>
