How to zoom in and out in an application or program.
To zoom in and out of your screen or application on your computer or laptop is very simple.
First click the screen you want to scroll in on. Make sure its the active viewing screen. (The one that is in front or on top of all other windows if more than one is open)
Then hold down the "CRTL" button on your keyboard. (You have two CRTL keys. You can use either of them)
Then press the dash key "-". The key is in between the 0 (zero) and the + (plus) key. Each time you press the - (dash) key you will zoom out.
Now if you want to zoom back in, or make the screen larger, press and hold down the CRTL key again, and press the key with the + (plus) / = (equals) sign.
