TIP #2

The function keys, or the F-keys, are pretty much vital in RuneScape for bossing and pking. And to set those up, you go to the settings icon and then go to the top right joystick, click on the functions options. And this lets you change the hotkeys to any F-key that you want. And using them really, really helps with bossing. It means you can do a lot more in a shorter amount of time.
