This came to me after playing Clinkz now that hes released,

What if you can toggle the fire arrows by holding down "W," or whichever button corresponds to the hero's ability as well as right clicking the ability. F.e. you might want to have it toggled on, but then immediatly turn it off because your mana is running low. As you know Clinkz or Trax have pretty good AS, so right clicking again on the ability will probably make you lose a few attacks, and having to stop attacking isn't always a good idea in combat or when attacking a tower in order to turn off the autoattacks.

Now here I might be missing some sort of way to do this that already exists, if so please inform me about it. If not, what do you guys think?
