Razer Analog V2 keyboard questions

I have a Razer Analog V2.

I would like to bind 'remap WASD to controller input' to a key on the keyboard, so I don't have to go into the software and click a button every time I want to use it - can anyone tell me how to do this?

I have the RGB set to 'spectrum cycling'. However, the keyboard's 'default' spectrum cycling - seen when booting the PC, for instance, before the Synapse software has loaded - seems to be brighter than when it's running through the software. I have brightness up to 100%. Any ideas on this?

Is there any way to map 'Sleep' to a button that doesn't involve pressing two buttons (Function and Pause)? I can't see the option in the remapping software.

Thanks!
