You can click on any word in the collocates list or any highlighted word in the concordance lines to see all entries in the corpus. By default, it shows you that word as a collocate. For example, if you are already looking at the entry for moonlight, then you can click on pale, window, or reflect to see them as collocates. By clicking on QUERY THAT WORD, you can switch to see the full entry for that word; for example reflect.
