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.
There are two magnifying glass icons at the bottom right corner of the editor that allow you to zoom in and out (plus and minus on the magnifying glass icon). 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 bottom and right 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.
