Automatic key selection

Do you know users that search through a lot of records by setting filters without choosing the correct key? I do too! It's a bad experience for the user and it takes a lot of time and it reduce the overall performance of the Navision system.
So why not let the system automatically choose the best key each time the user set's a filter? The catch is that you need to make a few program lines on each form where you want to use this functionality.

A short description of what to do on each form is entered in the Documentation part of the object. The download also includes a txt file of the object. The object is created in a 3.70 environment. The "Best key" function it self is created by the master him selves: Preben Rasmussen - Thanks!
