Starting today, Gemini users on Mac will be able to talk to the AI chatbot from any window on their computer simply by long-pressing the "fn" button on the bottom left corner of their keyboard. Google says Gemini will return a polished transcript by automatically removing "ums" and "ahs." Users can, for instance, highlight text in an open PDF document and then press "fn" to tell Gemini to create a summary for it. Google launched its native Gemini app for macOS in April, a day after it released the native Windows app. Now, it's rolling out this feature to all Gemini users on macOS around the world.
