How to Make the Infinity Symbol with the Keyboard

Updated July 19, 2017

Although computers are essentially extremely complicated math machines, it can be surprisingly difficult to type a complex equation on one. For example, due to the limited space available for special symbols on keyboards, the infinity symbol (?) is nowhere to be found. Thankfully, both Windows-based computers and Macs have a keyboard shortcut available which will allow you to type this symbol. Use this keyboard shortcut to insert the infinity symbol into math equations.

Hold the \"Alt\" key on the keyboard. If you have a laptop with a special key that must be pressed to turn certain letters into a numeric keypad, hold this key as well.

Type the digits 2, 3 and 6 on the numeric keypad.

Release the \"Alt\" key. The infinity symbol will appear at the location of the cursor.

Open any application that allows text entry.

Hit the \"Option\" and \"5\" keys on the keyboard simultaneously.

Release both keys. The infinity symbol will appear at the location of the cursor.
