Migration from VSE to Linux

Hi,

We now using Adabas/Natural on Linux (once IBM/VSE).
We use Putty as our terminal software, and NaturalOne ofcourse as our IDE.
What is the best configuration for NaturalOne & Putty for us (we as you called Bidirectional Language)?
Do we need change our maps according to this migration (on VSE we reversed our screen)?
How can we set the NewLine key press we had on the VSE?

With Regards,
Hezi
