I want to add a bunch of keywords to photos upon import. Under the Apply During Import window I see a text field for keywords, though I do not see a way to access all of the keywords that are saved within LR.
1. Is there a way to access all of the existing keywords fro this panel?
2. If I want to add multiple keywords to photo in this window, do I just type them out and separate them by a comma?
1. No until you start typing. Assuming you left auto fill on, it'll use previous keywords as you start typing.
2. Yes. You can also create heirarchies by using | between words, with a comma to finish. Start with the parent keyword first e.g. USA | New York, etc.
