A question from DH combat routine, he uses normal shoot w/o the skill on my panel?

When I used the DH to combat, I found that he could use the normal shoot without using any hatred. However, the normal shoot is not on my panel (not on button 1-4, left or right button of mouse).



So isn't it so "botty" using the skill without putting it on the panel? Can blizzard detect it?



Or maybe a more useful question is, how to use the normal shoot manually without the bot?



I'm sorry if I put this thread in a wrong place. I've used the search function but couldn't find any answer.
