If you are working on a small project or making a design with fine details, it can often be useful to be able to zoom in on specific parts of the design.
Zooming
There are two buttons at the bottom right corner of the editor (1) that allow you to zoom in and out: minus (−) to zoom out and plus (+) to zoom in. You can also use the keyboard shortcut "ctrl +" and "ctrl -" to zoom in and out, respectively. If you are using a mouse with a wheel, or a trackpad, you can hold the "ctrl" ("cmd" on Mac) key and scroll to zoom.
Panning (moving the camera)
You can either use the scroll bars on the right (2) and bottom (3) edges to move the view, or if you have a mouse with a wheel or a trackpad, you can scroll to move vertically and hold "shift" and scroll to move horizontally.
Resetting the view
At any point if you would like to reset the view to "home" (i.e. viewing the entire workspace), use the "home" icon at the bottom right corner of the workspace.
