Looking away from your screen and delaying commands while your eyes try to locate the right keys is a good way to die in PC battles.



Having to feel around isn't much better, but it leads to not having to look or grope around in the dark. So, if you still look at the keyboard, I'd suggest you glue dots or wire pieces to your keys for recognition (and don't allow yourself to look ever again). Use hot glue or water soluble glue or poster tack (something that you can remove later).



But anyway (back on topic), having just stumbled upon this instructable, I'm looking at my keyboard trying to come up with something clever...I'm not clever...o'well, gonna copy this and the spacebar idea too. Great ideas.
