Azimuth Elevation Tool
Revolves the camera about the center of interest in the perspective view.
The angle of a camera’s sight line relative to the ground plane is also referred to as its elevation; the angle of a camera’s sight line relative to a plane perpendicular to the ground plane is also referred to as its azimuth.
Select View > Camera Tools > Azimuth Elevation Tool > to set the Azimuth Elevation Tool options.
Yaw-Pitch Tool
Tilting a camera means rotating the camera up or down; panning a camera means rotating the camera left or right. The scene in the camera’s view moves in the opposite direction.
The angle of rotation up or down is also referred to as pitch; the angle of rotation left or right is also referred to as yaw.
Select View > Camera Tools > Yaw-Pitch Tool > to set the Yaw-Pitch Tool options.
Fly Tool
Lets you navigate your scene as if you were playing a 3D first-person perspective game. The camera flies through your scene without being constrained by any geometry.
- Hold Ctrl and drag up to fly forward or down to fly backward.
- To change the camera direction, release the Ctrl or Control key and drag the left mouse button.
- Tumble, track, and dolly are available while the Fly Tool is active.
Walk Tool
The Walk Tool lets you explore your scene from a first-person perspective. You can create sets and big environments, and then move through your scene using the Walk Tool's game-like navigation controls. See Walk Tool.
When Maya is in walk mode (hotkey: Alt + X), Maya's cursor changes to a multi-directional arrow 
and a heads-up display message appears at the bottom of the viewport.
