Keyboard to attack?

[Kmarkt]

Is there a way other than left-click mouse to attack? It's very frustrating to have to turn your character with the keyboard and attack with the mouse, as the monsters are constantly rotating to try and flank you. Thanks in advance!

Options should allow you to use mouse movement to turn your character. My default installation allows me to use the mouse to turn by moving the mouse left and right.
