Start search in the first window of Winamp Media Library

[anaxio]

Hi,
whenever Winamp is active and if Winamp Media Library is open and if ControlGetFocus doesn't contain Edit, then if I press any alphanumeric key I need the script to:
1) Go to Winamp Media Library
2) In the Library go to the second window (or "filter"). The Media Library contains at least two windows, the first being the Local Media tree. So I need the focus to get onto the second window.
3) Start searching (this is a native Winamp function).

Can it be done?
