Selecting controls

In “OrbitControls”, camera position is changed according to mouse movement while mouse key is pressed. Camera lookAt vector is constant in orbitControls.
In “pointerLockControls”, camera position is fixed and camera direction is changing according to mouse movement.
I want to fix camera position and change camera direction like “ponterLockControls” while mouse key is down . after releasing mouse key, both parameter position and direction will be fixed like “OrbitControls”
