Not sure how many don't know this, but you can hold Shift to fire from the spot without moving without a target. Very useful when kiting and you don't want to misclick in the wrong direction.
If you are a ranged class and you are like me, you'll love to use this ability to stutter step kite. Try rebinding the key to your spacebar though. It allows you to use your thumb much more easily than your pinky finger, and space isn't used for anything important.
Also, for classes like wizards that sometimes like to run into packs of mobs to nuke, there is a straight MOVE key that is not bound by default. Binding it to a key will allow you to attempt to run to your mouse cursor when used. This is handy as sometimes left clicking a spot might unintentionally fire your signature move at a mob when you don't want to. I bound the action to the ~ key, but you can use whichever key is most comfortable.
