I'm unsure as to why or how, but my cat has different chitters for each type of bird or creature that he's watching. The volume is also dependent on the size of the creature, so sparrows get a decently quiet "ch-ch-ch" sounds, while crows get a louder more crow-like "cha" sound.

The morning that he was making really loud unusual chirping was the morning that there was a set of vultures on the neighbors roof that he was watching.

Usually, though, I can reasonably identify the bird even if I'm in a different room.

It's just the Dewey Decimal System, so you could look up whatever topic you like to find what it would be classified under. There's thousands of topics that are covered here - there's a reason it's used for every non-fiction clarification in a library - that would be far too numerous to list on a single shelf listing. This library has chosen to prioritize the awkward questions as a way to help someone who otherwise may not know how to get help.

Alternatively, most libraries have a catalogue you can search by keyword and it will give you book results which will let you know where they are on the shelves. But again, that requires you to know that the catalogue exists and how to use it. It's always going to be easier to ask a librarian, who can make sure you find something to help.

I don't think I said that OP was wrong (in fact I'm pretty sure I agreed with OP that it was annoying as a fully abled user until I figured out what was going on), but to elaborate on my earlier point just slightly - once a horizontal slider element is in focus it will always use left and right arrow keys to move if they're pressed. Up and down always works to change the volume because there are no other elements when the video player is selected that are waiting for an input.

If they made the volume slider vertical instead of horizontal it would end up working actually better in this case (because the vertical slider would instead wait for up and down arrows), although that probably wouldn't look as "nice", but I'm not a UX dev so it could probably be jazzed up to look nice.

This is an accessibility function and happens because the volume slider has focus. If they made it so that left and right arrow keys always moved the video forward/backward it would break that accessibility and shut some users off from being able to use the website.

As annoying as it might be to someone who has full use of their mouse and keyboard it is imperative that websites can have all of their functionality accessed through something as simple as tab and arrow keys because that's all that some people are able to use.

Note that I'm in your boat and find it to be annoying and just something to remember to unfocus after changing my volume, but having just recently been going through some accessibility training I can understand why this happens.
