The 14 best computer tricks everyone should know

If there's one thing Reddit users are good at, it's coming up with clever tricks — especially on computers.
And in one post, a Redditor asked fellow users what computer tricks everyone should know. People submitted a wealth of tricks for Macs, PCs, web browsers, specific sites like YouTube, programs like Excel, and more. What they all had in common was that using them makes your computer life a whole lot easier and more fun.
We looked through the tricks and found the best 14, which are a mixture of useful and mischievous. 
Here they are:

Most people know you can hit the space bar to pause a YouTube video, but sometimes this causes it to scroll down the page if you haven't already clicked on the video. If you press "K," this will play (or pause) the video every time.
Hitting the "J" key will cause you to go backward 10 seconds, while hitting the "L" key will make you go forward 10 seconds.
