Eclipse PDT (PHP Development Tools) has the ability to quickly show the definitions of functions and methods by hovering the cursor over the parentheses of a reference. This feature is an extension of the typical docblock or signature reveal when hovering over a method or function call itself.
It's not as easy to hover over a parenthesis as it is to hover over a function reference, so invoking the tip can be a little clumsy. And there's another peculiarity with the feature too. Typically, the inline popups like this are "focusable" by moving the mouse from a hover into the pop-up. For these pop-ups though, they immediately disappear when moving away from the parentheses. Instead, use the F2 key to focus the pop-up. In spite of these usability matters, the feature is handy as a quick reference and is welcome.
It's possible that other Eclipse plug-ins have a similar feature to, so in order to get an idea as to whether or not this is a feature of the PDT plugin, the feature was tested with the Java, and JavaScript perspectives. The feature was only available while using PDT.
