Dictate Your Messages Using This Mac Keyboard Shortcut
Summary: Mac users who like to multitask: there’s a keyboard shortcut to turn on text dictation so you can talk instead of type. Just place your cursor where you want to enter text (it’ll work in any app where you can type), double-tap the Fn key, and start talking. The microphone icon will pop up to let you know that dictation is active. When you’re done with your message, double-tap Fn again. You can also click Done below the icon or press Return.
