    🚩Pro Tip: Type all the symbols like a pro

    Sometimes you need to type a character that isn’t on your keyboard, like an em-dash (—) or the copyright symbol (©). If you have a numeric keypad on your keyboard, you don’t have to find one and copy and paste, you can just do it! Here’s how:

    1. Hold down the Alt key on your keyboard.
    2. With the Alt key held down, type the four-digit code on the numeric keypad for the character you want. (Include the leading 0 if that’s required.)

      Note: This only works on the numeric keypad. This won’t work on the row of numbers at the top of the keyboard.

    3. Release the Alt key.

    Here’s just a few of the characters you can type with the Alt key:
