Auto Record Advance

Auto Record Advance

I need to enter numbers "heads down".
For this I created a sub form with one (text) field.
Now, after every entry, I need to manually hit the + ADD NEW button to be able to enter a new line.
What I need is, when the user enters data and then hits Enter (Carriage return), the record is Added and a new line is presented.

I looked into the scripting section but I can't find how to do this.

Anyone??  Thx!
