Calc function predictive type and autocomplete

I have figured out that enter is the equal to tab from ms excel.

Im just wondering if its possible to move it from enter to tab button as the movement when writeing formulas feels unnatural for me after years of useing excel.

Also the same whit the comma signs, is it possible to replace them whit ; or : ?

The Enter button movement from cell to cell is configurable. With a Calc Spreadsheet Open, Under Tools, Options, Click + for Libreoffice Calc, General, Under Input Settings, the first choice is for the Enter Button. See the picture.

Tab will still move horizontally.

For the comma signs, they may be language or region dependent. I don’t think they are configurable in LO. Perhaps if your decimal point in your Operating System is a comma, the formula separator may switch to a ;

You may also be able to type in a ; but it will be replaced by a comma.

The place in relation with separators is:
Menu/Tools/Options/LibreOffice calc/Formula - Separators.
