I hate having the FN key in the bottom left corner. Hate hate hate. I remap it back to CTRL. I instinctually reach for the last key when aiming for control, and it not being there really throws off my typing, and really really throws off my gaming.
What I find strange is that touch typing with the remapped "CTRL in the corner" works great, but when I look at the keyboard and try the same combination (usually for strange combinations), I press the "wrong" (Fn) key.
Welcome to the world of this particular dvorak user. If I don't look at the keyboard, I get dvorak; if I look at the keyboard, I get qwerty. Doesn't seem to matter what's printed on the keys.
