Just sharing an idea I had in mind. You know those results from Google's AI overview? If you click the reference link, it would point to a specific content in the web page, and it would have a text highlight.
(I've never really paid attention to Google's AI overview before, so this was new to me) 
It apparently uses scroll-to-text fragment in the url to achieve this.
So, I thought that this could be useful for referencing quotes/text snippets here in the forum. I think it's best application is when quoting from a long post.
Let's look at the difference. Below is an example of a normal snipped quote:
-snip- Bitcoin is free for anyone and freedom resides inside it; if you want to have control over your privacy and finances, all you need to do is to embrace it.
And here's the one with a specified text fragment:
-snip- Bitcoin is free for anyone and freedom resides inside it; if you want to have control over your privacy and finances, all you need to do is to embrace it.
If you click both links, the normal quote directs us to the start of the post, while the other directs us to the specific message.
To do this, just add
#:~:text={textStart},{textEnd} at the end of the url, where
{textStart} is the beginning of the text snippet, and
{textEnd} is the end of the text snippet. Then replace the quote parameters with the url tag inside double quotation marks (""). Here's the opening tag of the example above:
[quote="[url=https://bitcointalk.org/index.php?topic=5255623.msg54620797#msg54620797#:~:text=Bitcoin is free,embrace it.]GazetaBitcoin on June 14, 2020, 09:34:23 PM[/url]"]
If you find it too much of a hassle to edit the quote parameters, you can maybe just quote the message and use url tags instead like the one below.
-snip- Bitcoin is free for anyone and freedom resides inside it; if you want to have control over your privacy and finances, all you need to do is to embrace it. (Reference) It seems to work on most browsers. What do you guys think?
