If you have a keyfield you can create a capture link to do a lookup. If you have a search page and the keyfield is part of it, then you cannot apply the link here. So you need to know about the values of the key. This is not always the case: I have a table of companies with a numeric (autoinc) field as a key. I have a table with foreign key compid. In this table I cannot search for the company using it’s name because the field is numeric. I can create a link if I want to add/alter the record. But if I have a search page, I need to know the number. It’s very welcome to have a link button on this field if there’s a link created on this field. (hope I made myself clear enough)
