Button to temporarily turn off Mouse lighting?

Hello,

As title says. I love the ability to completely turn off the lighting on my K95 keyboard with the special key, but no matter how much I searched, I couldn't find any way to do any of these two things:

1) Either bind an action to some button that would turn off the Mouse lighting without switching its profile to a special 'dark' one

2) Or somehow force the keyboard button to not just turn off keyboard's lighting, but mouse's too

Any help would be appreciated!

Right click on a mouse button in CUE.

Pick Remap Key/Button.

For function pick "Corsair Hotkey."

Then select brightness.
