The name "PreTypedKeys" suggests that one may specify more than one key.
If this is more than just optimism on my part, given that PreTypedKeys is a string, what does one concatenate the keys with?
In my case, I'd like to do a 'free text' lookup for inventory items (looking inside description, all the category names, etc), and then given a small enough list (say the search only produces 3 or 4 results), present the user with a 'normal' Inventory search window where the 'PartNo' field has been pre-populated with part numbers from the aforementioned list.
