hey guys...I use a tablet to model in maya, and its very hard to me to use the default alt + mmb to pan the viewport....I changed the default Track Tool to the letter "S", however, when I press the "S" key it stays on the track tool until I press the "Q" key to exit the function. I really need to to create a script to this. So, just Pan/Track the viewport when the "S" is on press, then exit when I release it. Could someone help me with this?

Thanks in advance!
