Shortcuts

Some useful shortcuts I used:

• SHIFT + F : flying mode. Most useful to adjust your camera.
  • MW : zoom in/out.
  • MD : move around.
  • MLB : validate changes.
  • MRB : cancel changes.
• CTRL + [left|right] : Switch between UI perspectives.
• MMB + mouse move : modify 3D view.
• NumPad? 0 : switch to camera view.
