Version 1.3 adds drag and drop onto a document window, and a Scratchpad to store keywords that you use often. For 10.14.6 and later.
Second beta adds support for all metadata keys, has an extensive Help book, and saves results in a text file. Discover the keywords you can search for.
Automated image analysis and other tools store keywords in many different types of files. To search effectively for keywords, though, you need to know which terms have been used.
