using this tool, RemapKey, you can remap any key on your keyboard to be anything you want. On my laptop, I have to press Fn+F11/Fn+12 in order to adjust my volume. This is quite an annoying hassle, as a repetitive task, to have to use two hands in order to adjust the volume. So instead, I have remapped my F11/F12 keys to be directly volume buttons. A single key press is all that is needed now to change the volume.
Now, what if i need my F11 or F12 keys? I have used a tool called Asus Notebook Keys to remap what happens when i press Fn+F11/Fn+12 to be regular F11/F12 key signals.
