camera drag function

i see everyone dragging their mouse to the edge of the screen and then back to move the camera and i just have to wonder "does no one, not even the pros, know of the camera drag function.". i have mouse with two extra buttons and i find dragging my mouse to the edge of the screen inefficient and somewhat clunky and so i have a button which my thumb rests without me having to do anything out of the ordinary with how i hold my mouse set to the camera drag function. you press the assigned button and drag your mouse in the opposite way of where you want the camera to go, may sound counter intuitive but feels really nice and i didn't have to get used to it at all. all i do every game all the time is press right click then drag the button in the opposite way of where i am going, move the mouse back again , right click and repeat. it saves you dragging your mouse even further and i honestly don't even think about it, just like right clicking to move. please try it out and tell me what you think of it.
