Lets see some YouTube keyboard shortcuts for ease our video consumption experience:
Use keyboard key K to pause/play a YouTube video, instead of the SPACE key to avoid annoyingly accidental page scrolling with the latter.
J / L
Skip ahead 10 seconds in a video with key L, or J to skip backward by 10 seconds.
Skip ahead 5 seconds in a video with the Left Arrow key, or Right Arrow key to skip backward by 5 seconds.
HOME key to go back to the beginning of the video, or END key to skip to the end of the video.
Increase or decrease the volume of the video.
To mute or unmute the video.
Turn ON or OFF the closed captions.
Number Keys (1 to 0)
use 5 to go to the 50% mark of the video, or 7 to skip to the 70 percent of the video, 0 to go back to the beginning, and vice versa.
