how raspi-idle3 configure?

[Egon Mueller]

Hello,
is there a manual concerning the python3-ide on a raspberry / debian jessie?
- The menue bar and the items there would I like to have a little bit 
greater for better readability.
- After running a program is needed long search to return to editing 
window.
- ....

Where can read a beginner so simple things about handling the python 3 
idle3? I don't think about python programming, only about better 
handling the ide.

Thanks
Egon
