Autocomplete how to view all possible items

[Alberto]

Hi, I have severan Autocompletes fields and it works ok.
The filters are very very complex and depends one on another. Thats because I dont want to add a search button because Ill have to maintain another proc with this complex filters.
The user loves autocomplete but it wants the possibility of see all the items without typing any letter because there are moment in which they don remember which can be thhe possible items.
How can I do it?

If they haven't typed anything then it's not AutoComplete.
So in this case include a Lookup button on the field so they can do a lookup.

cheers

Thanks
FWIW... Ive found that if the user type spaces then the drop fills with all possible options, and its very usefull.
