What happened to the code reference panel from CS5?
I have been watching a CS5 Flash ActionScript tutorial, but I am using Flash CC. In the tutorial, there is a code reference panel to the left of the actions panel that has a list of all the possible code pieces, and when hovering over any of them, it shows a tooltip describing the code piece. Did they remove this panel in later versions of Flash, and if so, is there any way to bring it back? It would be extremely useful as a tool to learn ActionScript.
The following is a picture to show what I am referring to.
