Witches down one skill?

At the moment there are 8 skills you can use. My problem with this is that I am only allowed to use 7. I have to have my wand bound to my left mouse button because if I don't then I have no way of moving my character.

Example: If i'm a hero that uses a physical attack skill like dual strike, i can move and still have a skill bound. Essentially I would have to use Power Siphon or Elemental Hit or something on my wand to use up that skill slot and still be able to move.

Neither of these work with my build. Is there anything I can do so that I can have 8 abilities bound and still move like other players?

On my witch I have Arc bound to my left mouse button and am able to move freely. You just can't click on mobs or you will fire instead of moving, but that is the same with any skill and you probably aren't a melee build so you would want to be away from mobs anyway. What skill are you trying to use on the left mouse button?

Bind desired skill to left mouse.

When moving, click away from mob and "Hold down left mouse button"

drag mouse into desired location while moving as to not click on anything.

Now you have maximum skills available.

Edit: Figured it out. Thanks all!

Having the move only skill taking up a skill slot is also very annoying.
