Are you talking about the W+F skill? If so, you need to hold down W and control the direction using W+A (to turn left) or W+D (to turn right). This way you don't need to keep using the camera to control the direction (however it will influence it a little when you try to turn backwards, so you need to control the direction with W+A/D to "cancel" the camera movements that you don't want to follow).
