Hello There!

First i have to excuse myself for my extremly bad English. Sorry for
that.

I would like to ask a Question about a very special Excel-Function when
Programming Documents.
i was trying to make a sort of Database-Sheet with Excel. when now
someone wants to Enter some Data, i wished that the cursor jumps
automatically to the Next Cell that wa meant to contain user-Definded
Data when pressing Return or an Arrow Key. I know this function to be
present somewhere in Excel, but i totally forgot how to use it or how
it is named.

Does somebody Remember the Function?
I am very Thankful for every Help.

Greetings
