title: In eclipse package explorer, how can I expand a tree in one click?
body: <p>For example, I have a folder structure like this:</p>
  
  <pre><code>src
  └─test
      ├─java
         └─com
             └─google
                └─test
                    │  AllTests.java
  </code></pre>
  
  <p>in order to see file AllTests.java, I need to click many times to expand the tree. 
  I'm wondering if there is an option as "expand all" to expand the tree in 1 click.</p>
