I'd like to know if all the characters on the keys are backlit (the keys are, so there's no problem). I'm asking this question because the layout in the photos is not the CH keyboard and it's not possible to see it. I have the G 915 keyboard, and I had the unpleasant surprise of finding myself with characters like: ¦@#°§¬|¢'~][}{ _:; which are not backlit. Thanks in advance
