I like to come up with ideas and then see if I can get them to work, so I went around your reference a bit to see if it was plausible. Works really well, except, when I am holding another key, it kinda doesn't let go if I click my mouse. Example, I am moving forward with my Pally, I then click to focus on my Shaman's window and my Pally keeps on moving. Not sure if it is a bug or how that is supposed to work.
