title: Eclipse how to directly show a list of available functions
body: <p>Eclipse has a feature in which you write a classname followed by a dot, and a list of available public functions appears. But what if I want to see the functions of the class I am currently in? 
  The only solution I know is to write <code>this.</code>, select the function from the appearing list, and delete the <code>this.</code>.</p>
  
  <p>Is there any way to show the popup menu without writing <code>this.</code>, a hotkey perhaps?</p>
