title: SourceTree - Not sure how to go back to a previous commit
body: <p>So I'm fairly new to version control but managed to setup sourceTree with bitbucket relatively easily.</p>
  
  <p>I also now understanding basic concepts such as commit, push and pull.</p>
  
  <p>I can't however find any documentation (that doesn't involve text commands) on how to revert all my uncommitted changes at once to the last commit (not pushed). I can do it individually for each file but this is taking far too long.</p>
  
  <p>Many thanks!</p>
