#### Switching default Middle Mouse 3D View Controls to Right Mouse
53+
To match other 3D software, the Middle Mouse 3D View camera controls can also be switched to use the Right Mouse instead:
54+
- Shift + Drag RMB to Pan 3D View
55+
- Ctrl + Drag RMB to Zoom 3D View
56+
- Ctrl + Shift + Drag RMB to Dolly Zoom 3D View
57+
- Alt + Drag RMB to Rotate 3D View
58+
59+
Other controls that were switched to Middle Mouse:
60+
- Shift + Click MMB to Set 3D Cursor
61+
- Shift + Drag MMB to Transform Translate
62+
- Ctrl + Drag MMB to Lasso Selection
63+
- Shift + Ctrl + Drag MMB to Lasso Deselection
64+
65+
There is also a setting to switch the activation of Right Mouse Navigation mode and the 3D View Rotate keymapping:
66+
- Drag + RMB will now Rotate 3D View
67+
- Alt + RMB then WASD for Navigation Mode
