The 14 best computer tricks everyone should know

HBO

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:

Get back that tab you accidentally closed.

If you want to get back a tab you closed, just press "Control" (or "Command" on Mac), plus "Shift," plus "T," and it will magically reappear.

Only screenshot the part of the screen you want.

If you only need to screenshot part of the screen, there's a simple way to do it for both Windows and Macs.

For Mac: "Command," plus "Shift," plus "4" brings up the tool. Then you just drag the area you want.

For Windows: Just go to "Start" and then "Snipping Tool."

Easily repeat your last command in Excel.

If you press the F4 button in Excel, it repeats the last command.

Here's an example given on Reddit: "If you select a cell and highlight it yellow, you can then highlight any other selected cell(s) yellow by pressing F4."

Make a copy of a file by just dragging it.

All you have to do to make a copy of a file on a Mac is hold the "Alt" key ("Control" if you are using a PC) and then click and drag the file. This will make a copy that you can drop anywhere you want by un-clicking.

Reverse search an image in Chrome.

In Google Chrome, if you press "S" while you right click on an image it will do a reverse Google search. That means you'll be able to see where that photo is and where it potentially originated.

Pause YouTube with one click, or skip backward and forward 10 seconds.

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.

Move your window to any side of the screen, or to the next monitor.

Google

If you click the "Windows" key, plus one of the arrows (right, left, up, down), your current window will move to that side of the screen. 

Similarly, "Windows," plus "Shift," plus one of the arrows will move your window into whatever monitor is that way (right, for example).

Unfortunately, this only works for Windows machines.

On a Windows machine, hit "Windows," plus  "L" to lock your computer. This can be fun for pranks.

On a Mac click "Command," plus "Option," plus "Eject." (Or "Power" if your computer doesn't have an optical drive.)

Freak people out by rotating their screen.

If you press "Control" plus "Alt" plus one of the arrow keys, it will rotate your screen that way. Note: this doesn't work for all computers (and only on Windows), but when it does, it can seriously freak someone out.

Turn your browser window into a simple text editor.

If you want to bring up a basic text editor you can type in, just paste this into the address bar in your browser:

data:text/html, <title>Text Editor</title><body contenteditable style="font-size:2rem;font-family:georgia;line-height:1.4;max-width:60rem;margin:0 auto;padding:4rem;">

If you want to play a trick on someone, and send them a fake screenshot of something that never existed, there's an easy way in Chrome. First you bring up the console by pressing "F12."

Then you enter: document.designMode = "on"

After this, you can edit any of the text that appears on the screen.
