Google has revealed a new feature for the Gemini AI app for Mac computers that makes natural voice interactions easier than ever, while also responding in context to the window you’re working within. Google is commandeering the Fn key on Mac’s keyboard and a long press of that button, typically used to access secondary system shortcuts for the function keys, will summon Gemini into action. In a blog post, Google writes: “By long-pressing the Fn key, you can speak naturally into any window on your desktop. From there, you can ask the assistant to perform app window-dependent tasks after pressing that Fn button. Google says these include requests to extract and summarise information from a file, photo or document open on your desktop.
