Mapper style navigation

DEPRECATED: Walk Navigation in Blender 2.70 and later is better than this.

The Navigate Mapper Style addon lets you freely rotate and move the camera. It's somewhat similar to Blender's built-in Fly mode, but more responsive.
Note: This type of navigation doesn't really work in orthogonal view.

Controls

Do What	Use What
Move forward	W
Move back	S
Move left	A

Cancel	Esc, right mouse button (press), middle mouse button (release)

Setup

1. Open Blender's User Preferences window and go to the Addons tab.
2. Click Install Addon and specify the navigate_mapper_style.py file.
3. Enable the 3D View: Navigation for mappers addon.
4. Go to the Input tab.
5. Inside the 3D View | 3D View (Global) folder click Add New at the bottom of the list.
6. Expand the newly-added entry and specify view3d.navigate_mapper_style.
7. Assign a hotkey. This navigation mode can stay active:
   • Until you cancel it by pressing Esc or the right mouse button (if this is your preference, assign any key you like)
   • As long as you hold down the middle mouse button (if this is your preference, assign a combination that includes the button; I recommend Alt+Shift+MMB, which is not taken by default)
8. To make your changes persistent, click Save As Default.
