I have searched the Internet for an answer to this question, without success. Perhaps someone here knows the answer.
I have locality name keywords nested. When I look at the keywords for an image in Lr 6, "for Zions National Park", "Utah", I now have "Utah" repeated with an "<" pointing from Utah to Zions National Park. It was not like that in Lr Classic. It just showed each place separated by commas like all the other key words, while the nesting is shown in the keyword list section. What does this "<" mean?
The < indicates that the left side keyword is nested within the right side keyword.
Perhaps you have the dropdown menu set differently in the Keywording dialog box, that's why it appears differently.
