If you have a ThinkPad released 2013 and onwards, you may have noticed you have to press the Fn-key every time to use a function key (F1 – F12). Some people, e prefer to use the function keys above the media keys, and here is the solution to your problem.
Pressing Fn + Esc toggles Fn-Lock, which allows you to use the function keys without having to press the Fn-key every time. Press Fn + Esc again to undo this.
