title: Is there a plugin for Eclipse that immediately evaluates a highlighted expression?
body: <p>A colleague of mine uses Netbeans, and I noticed a tremendously useful feature it has in debug mode: it immediately shows what a highlighted expression evaluates to in a tooltip. I'm not sure whether this is a standard feature in Netbeans, but I would definitely find it useful in Eclipse as well.</p>
  
  <p>Does anyone know a plugin or a similar way of using this in Eclipse?</p>
  
  <p>EDIT:
  Eclipse provides tooltips for single variable evaluation and expressions evaluation in the expressions view. This is not what I need. In Netbeans, you can highlight an <em>expression</em> (possibly containing more than one variable) and it gets evaluated in a tooltip.</p>
