Dear Sanel, thanks a lot for explanation. Am 03.11.2020 12:44 schrieb Sanel Zukan:
this *is* expected behavior.
I assumed that. The "error" is just in front of the screen. But I tried to understand. I understand and like the behaviour now. No need to re-configure anything. TAB work in some very restricted situations where it is (in python meaning) allowed. e.g. you type this two lines def foo(): """ after hitting RET the cursor is in the next (3rd) line but on first character/column. Now you are allowed to hit TAB and it works a "Tab" (4 empty chars) are inserted. Hitting TAB again the cursor jumps back to column 1. Great! So intelligent and powerfull. That is why I migrate (my brain) from vim to emacs. :D btw: It would be great if you could add your answere here https://emacs.stackexchange.com/q/61497/12999
