How can one add a keyword or more to the folders / documents of the search result in the Binder?

Select the target documents in the Search Results, select the keyword(s) from the Keyword HUD (Project > Project Keywords ctl-shift-o) and drag them over the selected documents in the Search Results.

Yes, OK, thank you very much, anyway!
