I'm sorry but there is a part that does not make sense.
If there are Google and Yahoo button two or more buttons
How do you recognize two distinct buttons?
You can give an example to illustrate how to use it?

PostMessage win("tab_dialog" "#32770") WM_APP 1 0
PostMessage win("tab_dialog" "#32770") WM_APP 2 0
PostMessage win("tab_dialog" "#32770") WM_APP 3 0

,case WM_APP
,out wParam
