What is alpha in keyboard?

Could you please clarify what you mean by "alpha in keyboard"? Are you referring to the letters of the alphabet on a keyboard, or is there a specific term or function related to keyboards that uses the word "alpha"? If you're asking about the letters of the alphabet, they are typically arranged in a QWERTY or similar layout on the keyboard, allowing users to type words and sentences. However, if you're asking about a specific term or function, I'd be happy to provide more information if you could elaborate further.
