How do you make a small 6 on a keyboard?

To type a small (lowercase) "6" on a keyboard, simply press the "6" key located on the top row of the number keys. If you're referring to a superscript or subscript "6," you can use formatting options in Word processing software or text editors. For example, in Microsoft Word, you can highlight the "6" and then use the superscript or subscript option from the font menu.
