Redragon K585 Home Key Titty Bump Addition

I have a Redragon K585 gaming keyboard but I really wanted it to have a bump or a "titty" on the home key I use in Call of Duty Modern Warfare and War Zone. I'm used to real computer keyboards which have a bump or "titty" on a couple of keys to help find the home keys when using them without actually looking at them (you're not supposed to have to look at a keyboard when using it).
