/**
* Hotkeys are:
* numpad + and - for +-0.25x speed (shift = +-0.5, alt = +-1);
* shift+q for 1080p quality, ctrl+q for 720p quality, alt+q for 480p quality;
* x to open subtitles menu;
* r for replay when video is over (video container should be active);
* q and s for quality and speed menus (just open, no choosing);
* My first script posted, not familiar with TM's and YouTube's tricks, so eager to see informative feedback!
