title: Editing files from different git branches
body: <p>I am verry new to git. I cloned a project on my local server and I edit my files with TextMate.</p>
  
  <p>So, I had a branch called master. Then I created a second branch called local. I made somes modifications, added some files and commited them all. But now when I go back to my master branch, I am unable to edit with TextMate the ancient files (non modified master branch files). How is it possible to fix that? Am I supposed not to use TextMate?</p>
  
  <p>Best,
  Mehdi</p>
