Type Special Characters Using Only a Keyboard
In today’s computing world, there are a lot of special symbols and characters in use that just cannot fit onto a standard keyboard. Even as a hardware reviewer, I find myself consistently using the degree, one-half, one-quarter, copyright, and registered symbols on a regular basis. Many others have to use accented characters, such as when writing your résumé) on occasion, even if you are not writing in Spanish or some other language. There are even scientific symbols that one might use, especially if you are a student.
You don’t need to hunt down these characters in your control panel’s Character Map, use a special GUI control or copy and paste them from a web page… you can do it right from your keyboard, without a mouse and you can literally do it blindfolded. All of the special characters in existance are right there in your keyboard, all thanks to the ASCII standard.
ASCII (American Standard Code for Information Interchange, pronounced aski) is a character map between letters, symbols and a number. Since computers only understand numbers, the ASCII code is the numerical representation of what you see on the screen. The basic ASCII definition included 128 characters, of which 33 are non-printing (you’ll see a blank space on your screen).
The Alt key and numpad is used to tap into all of the hidden ASCII characters
The most common ASCII codes are executed when you press a single key on your keyboard. However, to access the symbols that do not appear on your keyboard you need to input a key combination.
In this example, we will generate an accented e (é) using only the keyboard…
1. Press and hold down the Alt key (AltGR on international keyboards, or Option on a Mac)
2. Input 130 on the numeric keypad (it MUST be the numeric keypad, not the numbers on the top row).
3. Release the Alt key. The special character é will magically appear after you let go.
You have access to the entire library of ASCII codes using this method. All you have to do is follow our handy chart!

I always forget about this! Is there any non-exploitive way of getting a copy of your chart?
I suppose I could book mark it and return every time, but how likely is that? Not very, not for me. I could screen shoot it, I suppose. I'm not going to go digging around in your page source as that is just plain rude. Well, let's say this, I save it for special occasions (bad ones) and you don't deserve that. Any suggestions? I could always look on Google, or IETF or ANSI or Microsoft or somewhere, but your chart is very nice.
Thanks for considering my request.
I use this chart all the time and have this page bookmarked. Sure there are other charts on the web, but yours is nice to look out, laid out well, and is copy-and-paste-able!
