changing brightness from the Level 20 RGB Titanium keyboard

[oldtrekky]

i know how to set the brightness of the backlight in a profile, but how can I change the current brightness from the keyboard itself. I have not found a hotkey that does it, even though the manual says there are 9 levels available. I am using a STATIC profile. Also, are there any keycaps that allow more light for the inscriptions at the bottom of the keys? I am specifically interested in the special characters to the right of the alphabetic keys.
