I have 3hr+ YT videos, so I chapter them out quite extensively. I've read in a couple places if I have too many keywords just grouped together they will all be ignored. Are my keywords being ignored...or are they even being crawled...through my chapters section? Also, is hashtagging in a chapter name good, bad, or not at all relevant?

example chapters:
