Word or expression for "the most important point" [closed]

Words like "crux", "essence", etc. refer to an idea that is a synopsis of a whole larger idea. But if one writes an article about some subject including many details about it, the most important point might not represent the whole article. Think of a description of a trip. There might be one detail that stands out, yet it is in no way the "crux" of the article.

So why not use "the main point"? Because it feels too verbose to be an expression. It feels like a sentence, like saying "this is the main point". Let's assume it's being used as a heading for some paragraph.

So, is there a word or expression that means "the main point" which does not indicate a summary, and yet does not sound verbose?

EDIT

It looks like some people see "the main point" to mean "crux" instead of looking at it more literally. So perhaps I should have used "the most important point" instead. Edited now.

EDIT 2

Enjoying the pool, even if it was the highlight of the trip, is not the crux of the article. But hmmmm, maybe "highlight" is the word I'm looking for.... or maybe "tl;dr", though that would be more slangy.

How about takeaway? From M-W:

takeaway: a conclusion to be made based on presented facts or information : a main point or key message to be learned or understood from something experienced or observed

Re your question, "So, is there a word or expression that means "the main point" which does not indicate a summary, and yet does not sound verbose?": Takeaway conveys the meaning of "the main point" without indicating a summary and without sounding as verbose as "the main point.".
