This question already has an answer here:
Example: I tried finding out about foldclose because it sounded strange to me that it isn't a binary setting but still only knows the value "all". I typed :h foldclose and landed on a description of the command :foldc[lose]. How do I find the help entry that describes the vim setting foldclose?
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
you can use :help 'foldclose to get the help for the option foldclose.
Find details about possible contexts in :help help-context
Use helpgrep and then navigate through the matches either directly in the quickfix window that is opened or use :lnext and :lprevious
