  • The First Row of Keys
    Keyboards are similar/ to the typewriters of the past! You had the letters, numbers, shift, backspace, spacebar on them, and they are still present on your keyboard. Your carriage return is now called "Enter". The first row of keys. ESC You can use the ESC (or escape key) in most programs to back out or quit whatever you happen to be doing at the time. Most of the time I see people use this with video's for example! They want to see videos in FULL screen mode, and when they are done viewing they will hit the ESC key to bring the screen back to normal size. The F Keys - Functions Keys If you look to the top of the keyboard you will see keys that have 'F' and a number on them. They are called function keys. Typewriters didn't have these. You may use some of them from time to time and others you may NEVER use! F1 F1 you can press to bring up the help menu. Alot of times if you are working in a program, and you need to reference something you can click that F1 for help. If you are browsing the internet, and use F1 your help menu for your system will come up! Try it now to see what I'm talking about! F2 Not used that often! You can use this function when you rename documents. For example, lets say you have a file you made named 'my computer basics' and you hate the title! You want to change that title to something you like better! You click that document, and hit F2 and it will allow you to change that document name.
