I've been logging, organizing, creating keywords for a new doc. I'd like to be able to search my entire library for particular keywords. I see in older posts for older versions of FCPX one could highlight a series of Events, click the key and enter the keyword. That doesn't seem possible. Individual Events cannot be highlighted, only clips I've found.
To search for keywords across events, create a library-wide smart collection which contains those keyword collections. When positioned at the library level, do CMD+F, then add a filter criteria for keywords, select the keywords you want and save that as a new library smart collection.
