TOSHIBA Function Key, developed by TOSHIBA Corporation, is a system utility for Toshiba laptops that enables and manages Fn (Function) key shortcuts and their on-screen indicators. It provides quick access to common hardware controls—such as display brightness, volume, wireless radios (Wi‑Fi/Bluetooth), touchpad enable/disable, keyboard backlight, external display switching, and Eco power mode—with clear on-screen feedback when you press the corresponding Fn combinations.
Designed to run quietly in the background, TOSHIBA Function Key integrates with other Toshiba system components and may require the Toshiba System Driver or related packages. It is typically preinstalled on Toshiba notebooks and helps ensure that hotkeys and on-screen displays work as intended. If Fn shortcuts or their overlays stop working after a system update, reinstalling this utility can often restore full functionality.
