The Internet Gradually Enters People's Lives, The Keyboard Tricks you Should Know

The great thing about computers is that they can increase your productivity extremely quickly. But there are still many people who don't know how to use a computer keyboard.
I'm talking about keyboard shortcuts. To perform keyboard shortcuts, you can press two, three, or sometimes four keyboard keys at the same time. A quick shortcut does the same thing as moving the mouse around the screen and clicking multiple menu or search buttons.
There are dozens of them, from pressing Ctrl+A to select everything in the window to pressing Ctrl+B to make the selected text bold. Press Ctrl+F to find words in a document or web page. If you want to print something, press Ctrl+P. (Most shortcuts are the same on the Mac, you just use the CMD key instead of the CTRL key.)
However, the six shortcuts below are the most important. Get in the habit of using them and your mouse will start collecting dust in no time!
CTRL+S (Save)
The first thing I emphasize to anyone learning to use a computer is to save your work often! You never know when a program you're using or your entire computer will crash.
Over the past decade, many programs have included an auto-save feature that saves your work every 5 to 10 minutes. This is fine as a last resort, but I still prefer to get into the habit of saving manually. It comes in handy when you're using programs that don't have autosave.

That's why the CTRL+S shortcut is so handy. It works with just about every program in existence and takes only a fraction of a second to type. You don't have to take your hands off the keyboard and move the mouse cursor up to the "save" icon.
When writing, I usually press CTRL+S after every few paragraphs or whenever I stop to think about a new idea.
CTRL+Z (undo)
One of the best things about using a computer for content creation is the undo feature. Using typewriters, handwriting, or traditional photo manipulation, eliminating errors is a major process.
Using a computer, the Undo button gives you the freedom to try and make mistakes, and change it back if you don't like it. I use it all the time when editing photos.
Many computer users don't even realize the undo feature exists.
Using the CTRL+Z shortcut, you can undo mistakes very quickly. Pressing CTRL+Z multiple times will usually undo the last few changes. If you step back too far, press CTRL+Y to redo.
CTRL+C (copy), CTRL+V (paste)
Another joy of using a computer is copying and pasting. It makes moving text, photos, files, folders and everything else a breeze.
Every program has a copy and paste icon, and if you right-click files and folders in Windows, you'll see copy and paste options. However, for those who do a lot of copy and paste, keyboard shortcuts can save a lot of time.
Just use the mouse to select what you want to copy, press CTRL+C, click where you want to paste, then press CTRL+V. you are done!
Bonus tip: If you want to move something instead of copying it, use CTRL+X (cut) instead of CTRL+C.
CTRL++ (zoom in)
Many websites and programs are difficult to read due to the larger, high-resolution monitors of laptops and desktops. The text looks too small.
Instead of getting close to the screen and squinting, press CTRL++ (it's a plus sign) a few times. This will increase the zoom level of most browsers and some programs. To zoom out again, just press CTRL+- (this is a minus sign). To reset the zoom level to 100%, press CTRL+0 (ie zero).
Bonus tip: If you already have one hand on the mouse, you can also hold down CTRL and roll the mouse wheel to zoom in and out.
CTRL+ALT+DEL (also known as "Three Finger Salute") or CMD+OPT+ESC (OS X)
Years ago, this was the first keyboard shortcut most people learned. In the old days of computers, it often happened that if the computer was running fine, it would restart your computer. You can solve a lot of problems with these three keys.
Bonus History: CTRL+ALT+DEL was first added to computers in the 80's by IBM engineer David Bradley. He wanted a way to quickly restart a locked test system. Ironically, he never intended for the public to actually use it.
On modern computers, CTRL+ALT+DEL either brings up the Windows Task Manager, or a list of options that includes the Task Manager. Task Manager is useful for killing running or unresponsive programs. Plus, you can see what's slowing down your system.
If you're on a Mac, it's not uncommon for programs to freeze and you'll see spinning beach balls. When this happens, press CMD+OPT+ESC, select the offending program and force quit. Restart the program and you'll be on your way again.
