Seriously, the amount of times this happened to me is astounding.

Pull up a YouTube video. Adjust the volume at the start. After playing for a while, I want to skip forward 5 seconds, so I press the right arrow. The video does not skip forward, so I press it again. I press it again, and in 4 seconds, I reach maxiumum volume.

Only at this point do I realize that, ah, this is part where YouTube interprets my right arrow as volume adjustment again, and I have to click on the play button or on the video itself to pause and play again, and only then will the right (and left) arrows mean what I think they mean.

I have never, ever - EVER wanted to use right arrow as volume up and left arrow as volume down for a YouTube video. not a single time in (almost) 20 years! And it does not even make sense from a usability standpoint, since the up and down arrows are already adjusting the volume up and down at all times, regardless of which part of the player is “active” (it should always be the play button. Fucking always).

The solution would be so simple, it hurts. Have the left and right arrows always mean 5 seconds backwards and forwards, as the up and down arrows already mean volume up and down. There is absolutely no need to switch the action of the left and right arrow, depending on if you clicked on the volume adjustment first. Oh well, chalk it up to “things I will never understand”.
