On many laptops, the function keys perform actions such as adjusting the laptop's volume or screen brightness by default. To make these function keys perform their operating system-specific actions, you must press and hold the "Fn" key before pressing the function key. This also applies to games such as "RuneScape" that utilize the function keys. If you want to use the "F5" key on a laptop to open your Attack Style menu in "RuneScape," you must use the "Fn" key to do so.
