HP-Prime: Documentation & Tutorials

[OlidaBel]

Hi,
I would like to know....

1- How to begin "from zero" with Python on Prime ?
There is no "python" reference in the officiel pdf.
Where to start ? something to install, to configure ?
I checked also here "HP-Prime: Documentation & Tutorials"
https://www.hpmuseum.org/forum/thread-818.html ).

2- Scrolling speed in the text editor on the physical Prime , is there a way to speed up key repetitition ?
Scrolling through text is too slow, it's about 5 repetitions per second.

thanks,
