I like the option to use F1, F2 etc. as standard function keys by default. However, I would like to have the ability to customize that, to select which keys operate as standard Function keys, and which keys use the other features. For example, I would like to have F1 and F2 operate as standard function keys (because I use them often in Excel), but all the other keys to use their assigned application functions like mic mute, volume up, etc.
