Sorry, I don't understand what you mean. 

I know the article is called XYZsomething, I enter XYZ in the lookupfield
(datasource = command line, listsource = articles) and push up and down to
scroll to the one that has "round corners" in the description field that is
displayed in another window (or panel) displaying ListSource. It is XYZ5, I
press enter and my field is updated. That is how it works in Delphi.

I'm familiar with Master/Detail, thank you. This is about scrolling in a
dataset while selecting field data in another dataset. The emphasis is on
while selecting (before posting) and not after entering data as in
Master/Detail.
