YouTube arrow keys FIX

This is a userscript for web browsers to:

• make YouTube keyboard controls (arrow keys) more intuitive,
• fix annoyances like focusing volume slider and progressbar,
• make Tab-navigation more user-friendly by highlighting focus on player buttons.

Installation instructions below.

Features

YouTube player keyboard shortcuts will work consistently:

• Left,Right -> jump 5sec backwards / forwards
• Home,End -> jump to video start / end - ONLY WHEN page is scrolled to top, otherwise scrolls page
• Up,Down -> volume up / down - ONLY WHEN page is scrolled to top, otherwise scrolls page
• Can't be focused: video player, volume slider, progress bar, fine seeking bar, subtitle

Global keyboard shortcuts, unaffected:

• Space -> play/pause on the whole page, not only when player is focused
• K -> play/pause
• C -> toggle closed captions (subtitles)
• M -> mute
• T -> theater mode
• F -> fullscreen
• +/- -> change subtitle font size
• 0-9 -> jump to 0%-90%
• J,L -> jump 10sec backwards / forwards
• , -> previous frame (when paused)
• . -> next frame (when paused)
• Shift-, -> speed -0.25
• Shift-. -> speed +0.25
• Shift-N -> next video
• Shift-P -> previous video
• / -> focus searchfield
• ? -> show keyboard shortcuts
• ENTER -> push the focused button

Fixes the following awkward behaviour of YouTube player controls after clicking them (making the individual control focused):

• After clicking the progressbar Up/Down will jump in the video instead of changing the volume.
• After clicking the volume slider Left/Right will change the volume instead of jumping in the video.
