Musa Compliant - ™ The Musa Academy For more information on the Musa Alphabet, visit www.musa.bet. Musa Keys is the easiest way to enter Musa text into a phone or computer. When you receive Musa text in a message on your phone, it will normally show as “tofu”. To read it, select the message and copy it to the clipboard, then just open Musa Keys. You will see the message, with Musa text correctly displayed, and you’ll be able to respond to it using the Musa keyboard. To enter Musa into your computer, you need the Musa Keyboards agent program. Both the computer and the phone need access to the same WiFi network, and you’ll need to have a Musa font installed on your computer to see the letters. The Musa letters you type go directly into whatever program you’re using: a word processor, an email program, a website, whatever – just as if they’d been typed on your hardware keyboard. While it is connected, you can continue to use your hardware keyboard to enter non-Musa text, and of course your mouse continues to function. And the agent itself functions as an onscreen Musa keyboard. Musa, Musa Compliant, and the Musa logo are trademarks of The Musa Academy PBC.
