Hi,
if the  Autocompletion window comes up, there can be a second window on the right side, which shows the source code of a focused method. I have tried to find where this window is triggered in the source but i cant find it.

So I have three questions and maybe someone can help me:
1. How is this second window named ?
2. Around which source code is this second window activated?
3. Where is the text which is shown in this window processed .

Maybe someone can give me a idea.
thx and regards
