Adds keyboard shortcuts [ and ] for liking and disliking videos, B and R to Back up and Restore position, H to use picture-in-picture, { and } to change playback speed.
Yup, was about to post, the shortcuts no longer like/dislike. Hope it can be fixed.
As MattSurgeon says, replacing 'ytd-segmented-like-dislike-button-renderer' with 'segmented-like-dislike-button-view-model' on line 164 fixes. Hope the author can update the main script. At least can use this workaround for now.
The PictureInPicture keybind is also broken, however fixing that seems a little more complex. document.pictureInPictureElement, document.exitPictureInPicture() & video.requestPictureInPicture() no longer exist, although there's still some (dead?) YT code referencing them...
I was able to find document.querySelectorAll("button.ytp-pip-button"), which has a click event listener that calls the aforementioned dead code, however calling .click() has no effect. Therefore I suspect they're listening for taps/clicks some other way but have left the old (non-functional) click handler in for now.
YouTube have changed their HTML again, breaking the like/dislike shortcuts.
ytd-segmented-like-dislike-button-rendererhas been replaced withsegmented-like-dislike-button-view-modelThe rest of
findLikeDislikeButtons()still appears to be working.
