It took me a while to assemble all of these get them looking good.Īs a developer, when I search for these codes I often get results that are image-based. (Note: this does not include the many, many characters from non-western European languages – otherwise it would be 100,000s of codes long.)īelow is a nice ASCII-formatted table of the most commonly-used symbols and characters. These Alt codes are also helpful if you have a keyboard with a stuck or missing key.īelow I will break down the entire list of alt keys by category. You can type a lot of characters that may not have a corresponding key on your keyboard – such as European language alphabetic characters, ASCII symbols, and even Chinese characters (also known as Hanzi, Kanji, or Hanja). Lastly, release the ALT key and you'll get the infinity sign(∞) on your notepad.In Windows, you can type any character you want by holding down the ALT key, typing a sequence of numbers, then releasing the ALT key. So, firstly, we have to press and hold the ALT key then type 236 using the numeric keypad. The ALT code for the infinity sign(∞) is 236. Let's try it by example to make it clear. Type the ALT Code on the numeric keypad.Make sure that the ALT key is working perfectly.

Firstly, turn On the NumLock or Numpad if it's Off.

After eliminating all these problems, the latest Windows machines are using the Unicode system. However, the latest systems use Unicode because the ANSI had some compatibility issues. It's called ANSI Codes which were later changed to Windows ALT Codes. The code which starts from '0' represents the new set of codes. After that Microsoft developed their new set of codes along with the previous one. BIOS is a process that interprets the user's action and prints the corresponding symbol at the cursor's location.

The interpretation takes place in the BIOS. This whole concept was at first developed by IBM and worked on Microsoft Windows Computers. We have explained the step by step process in the next section. It should be typed from the numeric keypad while holding the ALT key in order to type that character. In a Windows computer, holding the ALT button on the keyboard activates a list of special characters known as ALT Codes.
