Camera control options for Unity users, who became UE4 users

Hi all, i worked in Unity ~6 years and now it’s very difficult to start working in UE4. I have many troubles with camera control in UE4 Editor. In Unity middle mouse button working not like in UE4 and on the contrary. Can you analyze Unity and made control options for Unity users, who became UE4 users? Please!

In Unity:

  1. Middle mouse button move camera only on 2 axis, in UE4 on 3 axis
  2. Middle mouse button have inverted controls. Moving mouse with MMB left - camera moving right
  3. Pressing LShift will increase camera moving speed while it pressed
