How to use shift to dodge?

I have been playing for some hours but there is something I find a bit annoying.

I'm playing on Keyboard mouse, so Shift is to dodge. But, unlike other games, when I click Shift it just switches to some kind of Dodging mode. Then, when I go left or right he dashes there. When I click Shift again it deactivates this Dodging mode, which means it does not really dash then.

What I want is that when I click Shift he dashes. That´s it. And that is how I try to play, but many times I click and he does nothing because I'm really just deactivating Dodging mode.

Is there a way to change this?
