Gemini's fn-key shortcut makes it a system-wide agent on macOS

Google's Gemini for macOS now lets users long-press the fn key to summon the assistant from any window. An opt-in mode lets it read on-screen content and act across multiple apps, with voice dictation that strips filler words. The rollout is worldwide but English-only, positioning Gemini as a system-wide agent competing directly with Apple Intelligence.
