Why did you add this specific filter query and not one of the 1395 filter queries that are not mentioned on the page?

[mordv]

Same reason others were added - picked randomly.
There are only two L2 to which L3 can be applied, so I added caption_entities - thats the point of PR
It also plays nicely with this line

bot.on("message::url"); // messages with URL in text or caption (photos, etc)

Sorry for the insane delay, I really don't have enough time for OSS recently. This can still be merged, but I don't fully agree yet:

How about this instead?

Suggested change

	bot.on("message:caption_entities:url"); // captions containing a URL
	bot.on("message:entities:code"); // messages containing a code snippet
	bot.on("message:caption_entities:code"); // captions containing a code snippet

This is inconsistent with the other rows. The point here is to show how a single query is built up in three parts. Adding a second random query is confusing.

Let's revert.

Suggested change

| `"message:caption_entities:url"` | `"message"` | `"caption_entities"` | `"url"` |
