title: SourceTree: how to do a git diff in the opposite direction?
body: <p>How can I do a <code>git diff</code> in the opposite direction in the Atlassian SourceTree desktop app?  In other words, how do I get SourceTree to do <code>git diff b a</code> instead of <code>git diff a b</code>?</p>
  <p>e.g., if my commits are in this order in my commits pane:</p>
  <pre><code>  3333
    2222
    1111
  </code></pre>
  <p>and I select 3333 and 1111, it will show me a diff of changes from 1111 to 3333 (i.e, <code>git diff 1111 3333</code>).</p>
  <p>How do I make it do a <code>git diff</code> in the other direction, so that it's a diff of changes from 3333 to 1111 (i.e., <code>git diff 3333 1111</code>)?</p>
  <p>(NOTE: this question is specifically about how to do this in the Atlassian SourceTree desktop app, <strong>not</strong> how to do it in git in general.)</p>
