Where is the 'To' list form?

I am using DWA and want to make a change in the search field of the ‘To’ list form. However, I can only found the form for Client, not for DWA. Could anyone tell me where is the form? Thanks!

Subject: use dw search…

in the upper right corner change from ‘All of DW’ to ‘Lotus’ and enter ‘customize dwa’.

there is a bunch of docs:

This is perhaps what you need:

Subject: Still don’t understand

Sorry, I still don’t get it. Since I am using DWA6.5 and jump to DWA8, I got somewhat confused. I need to change the search field in the address form from a text field to a drop-down list field. But the (wAddress) seems only works for the Client. Where is the form for the DWA8. Thanks a lot!
