I cannot figure out how to use the Fn button, I had the same problem with my D90 so the problem is me. I have followed instructions from various sources to no avail. For instance, I want to use the horizon line when Fn is pressed but when I set it up for this and press Fn nothing happens. I must be really really stupid. This button seems to be very useful if I could only get it to work. If anyone has a step by step guide I would be very grateful.
Thanks
Brian
