title: IntelliJ how to zoom in / out
body: <p>The IntelliJ keymap says:</p>
  <pre><code>Zoom in: Keypad +  =  
  Zoom out Keypad - - 
  </code></pre>
  <p>But they have no effect. Anyone have this working?</p>
  <p>New info: Now I have added more key-bindings:</p>
  <pre><code>Zoom in: Alt-Shift-= 
  Zoom out: Alt-Shift-minus
  </code></pre>
  <p>But these still have no effect. Does zoom in/zoom out even work at all in IntelliJ?</p>
