im a newbie here and am adjusting to the layout on the macbook keyboard. I find it very nice to type on and got used to the keys really fast. One thing is im used to reaching over with my pinky to use the up and down arrow keys. The down arrow feels like it is either smaller or slightly more depressed...when I tilt the computer on an angle I can see it is. It seems like I will get used to it and is just a design to prevent hitting both at same time? Is it normal or is my new arrow key defective?
