Frequently asked questions
How do I use Alt codes?
Turn on Num Lock, hold the Alt key, type the number on the numeric keypad (not the number row), then release Alt. The symbol appears where your cursor is.
Why do Alt codes not work on my laptop?
Alt codes need a numeric keypad. On laptops without one, use the on-screen keyboard, the emoji and symbol panel (Win + .), or copy the symbol from this page.
