title: Test old commit in Git Repository
body: <p>I currently have a Project(JavaScript) with a bug in it and I am sure that I fixed it sometime ago, now my Question is how to revert to an old commit and check that Version on my localhost.</p>
  
  <p>But I do not want to loose any changes in my git repo I just want to check how the Project look at commit X, how do I manage that.</p>
  
  <p>I am using gitkraken as a gui.</p>
