How to toggle between fn keys doing f1-f5 or brightness/volume

Hello,

I own an HP Envy Notebook PC (datasheet here: http://www8.hp.com/h20195/v2/GetPDF.aspx/c04952229.pdf). At the moment, pressing the f1-f2 keys activates their secondary function, so for example turning the brightness/volume up/down. As an avid gamer, using the f-keys is beneficial sometimes, but the only way I can find to swap the f-keys from brightness/volume to the actual f-keys is by rebooting, going into the BIOS, and changing the configurations in there. Is there a simpler way to do it on my computer without having to restart?

According to https://support.hp.com/us-en/document/c02035108 when you set the action key mode to 'disabled' in the bios they function as normal F1-F12 keys, but work as action keys when you hold down the Fn key. The Fn key effectively acts as a 'shift' key for the function keys. Does this work for your model?

If you haven't already check the following to see if you any Fn Key options ...
Control Panel > Keyboard > Hardware Tab > Options
Control Panel > Windows Mobility Center.

Note: Didn't see it for you laptop, but watch out for Fn Key Lock (Fn Key+Esc) ... it has bitten me in the butt more than once :)

Ideally I'd like to not have to press the fn key to use the actions as opposed to the functions. Rather I'd just like to toggle fn lock on or off. A metaphor would be holding the shift key to write capital letters when I really just want a caps lock key.
