Navigating the 3D Viewport (Laptop/2 Button Mouse)
If you don't have a 3-button mouse easily available, that's alright. You can still navigate Blender's 3D viewport with a trackpad or a 2-button mouse. In this video, we'll look at some ways to make movement significantly more effective without a 3-button mouse.
However, I do strongly recommend getting a 3-button mouse if you plan to work with Blender more in the future.
