3 Ways of Moving Around the Viewport

1. FPS Controls: Those who are familiar with fps controls will find moving around within the viewport very easy. You can use the basic fps controls to move around within the viewport, these are 'W' to move forward, 'S' to move backwards, 'A' and 'D' to move left and right. These are quick panning tools and used in conjunction with the mouse this is probably the easiest and quickest way to move around.
2. Mouse Controls: You can use the right-click on the mouse to look around. This is a convenient control when used with the fps controls. The scroll button, if clicked is used for panning. Scrolling the mouse makes you go back and forwards.
3. Move Faster: You can move around faster by holding the shift button in combination with what ever movement style you want (mouse with keyboard or just the mouse).
