Search Provider in IE7 supports the Open Search mechanism. IE7 have some control elements (which are locatedin upper right corner by default) to work with added providers.

I want to find answer for next question:

1. How can I open from my custom Add-on (toolbar) the "Change Search Defaults..." Dialog Is there some API function to do this

2. Firefox, for example, saves an icon for each Open Search element. Do IE7 provide the same functionality

Thanks a lot.
