HTML5 Video Keyboard Shortcuts插件描述

Tired of Chromes primitive builtin HTML5 video player?

This extension adds an extensive list of keyboard controls to improve your viewing experience. The shtcuts are only active on videos with the default controls enabled, so dont wry about them messing up YouTube  other custom video players. To enable controls ( keyboard shtcuts) on videos that dont have them, just rightclick the video in question  select "Show controls".

Note that this extension is only meant to affect Chromes native HTML5 video player!
