[racket] How to disable a couple of things in drracket

Hi,

In DrRacket there are two features:

1. When you mouse over a symbol and arrow and a popuup show the source
of that symbol.

2. When the cursor is over a symbol if there is documentation for it
this arrow pops up in the upper right hand corner.

How do I disable each of these? I looked at every settings in the
preferences maybe I'm just not seeing it.

Best wishes,
