More About Alt Codes

Alt codes are used to type symbols and characters that do not have a dedicated key on the keyboard in personal computers running the Microsoft Operating systems. You can do this by pressing and holding the Alt key while typing the alt code (a number that identifies the character), using the keyboard numeric keypad.

For Example, to type µ using the Micro Alt code of 0181: first, ensure that your NumLock is turned on, then press and hold the alt key while you type the code on the numeric keypad. Then release the Alt key.

Other operating systems like the Mac OS have a similar or extended form of this Alt code feature which I’ll explain soon.

Rules for using the Micro Alt Code

  • You must press and hold the Alt key before typing the Alt code.
  • You must use the numeric keypad on the right of the keyboard to type the alt code.
  • Since you are using the numeric keypad, the NumLock must be turned on. Turning off the NumLock means the numeric keypad is disabled, and hence no numbers can be typed using the num pad.
  • If you are using a laptop without the numeric keypad, you should first turn on the hidden numeric keypad. On most laptops, you can turn this on by pressing Fn+NmLk keys simultaneously. Not all laptops have the hidden numeric keypad. If it seems like you, then you cannot use the alt code method to type the Micro symbol with your laptop unless you connect an external keyboard that has a numeric keypad.
  • You should also understand that not all symbols can be typed with the alt code depending on the document you are working on. Some of the alt codes work only in Microsoft Word. However, the Micro alt code works anywhere on Windows such as text editors, on the web, forms, and so on.

Micro Symbol Alt code shortcut for Mac

The alt code method of typing symbols is very popular on the Windows operating system.

However, the way you use alt codes on Windows is very different from that of Mac. Most people even think that it’s impossible to use alt code shortcuts in Mac.

As you may already know, the standard apple keyboard also has two alt keys. They are named as Options or with a small “alt” label. Though, some of the newest Apple keyboards such as the Magic Keyboard no longer include the “alt” label. The Option key also being the Alt key on the apple keyboard means that it can be used as an Alt key with non-Mac software.

Does it mean that you can press down the Option key while you type the Micro alt code on your Mac keyboard?

The answer is no.

Apple has its way of doing things. So instead of using the Alt or Option key with difficult-to-remember number codes like Microsoft Word, they combined the alt key with some other keys that will make shortcuts easy to remember.

So, if you want the Micro Alt code for Mac, then it is the shortcut you may already know, which is OPTION + M.
