Custom 'button' to execute a Search

I need to add a button to one of our BAQ report selection screens.
The button would be labelled as 'Attribute Search'.
On click, I would like the search screen for the Attribut table
to popup. The search button is for informational purposes only.
There is option field setup as a value list. I would like the user
to be able to look at valid attribute codes via the 'Attribute Search'
button. Does anyone know how to do this? Thanks! 8.03.407
