Usage of NextControl property to speed up data entry

I have a customer who wants the following in Sales lines:

After entering the Quantity he wants teh system to automatically jump to the next line and lands on the "No." field to enter another Item number if available.

Any ideas on how to do that??

Just change the NextControl on the columns. So Control 1 will jump to Control 3, Control 3 will jump to Control 1.

set the NextControl of the QTY field to the ID of the No. field
