F10

F10 is a designation used in different contexts, most commonly referring to the F10 function key on computer keyboards. The F10 key is located in the row of function keys at the top of most keyboards and is used to trigger program-specific commands or to access the application's menu bar in many operating systems. The exact behavior varies by software and hardware; on many laptops, the Fn key must be pressed to access the traditional F10 function. In some environments, F10 is also used during startup to access boot menus or BIOS/UEFI settings, with the specific key and procedure varying by manufacturer.

Beyond keyboards, F10 serves as a model or variant identifier in a range of products, including electronics, automotive parts, and industrial equipment. Short alphanumeric designations like F10 are commonly used by manufacturers to label generations, configurations, or specific features, so the precise meaning depends on the issuing company and product line. In military and aviation contexts, the F-prefix denotes fighter aircraft in many countries, but an “F10” designation is not universally standardized and may appear as an internal code, a project designation, or a regional label rather than a single, widely recognized aircraft type.

In summary, F10 is a versatile label whose exact meaning depends on the domain, with the function-key usage being the most widely applicable reference for general computing.
