Prezi

This means that the top left 'Bubble' menu is centered around the Zebra icon, and you can see a grid on your screen. This is the default state when Prezi starts.

Pan the canvas. (Drag means press and hold the button, while moving the mouse - you will see a smal clenched fist appear when you do this.)

If you don't see a Transformation Zebra, you can drag anywhere, even over objects. If you see the Transformation Zebra, you should not drag on the Zebra - since that will move, scale, rotate the selection instead.

Zoom around the mouse pointer. This means, that you can point to an object, scroll, and prezi will zoom to that object.

Alternating zoom in/out while moving the mouse is a good way to navigate even without panning.

Zoom in/out around the center of the screen.

When in Show Mode:

This means that the screen has no grid and the bubble menu disappears. Click on 'Show' in the bottom right of your screen to get there.

Zoom in to that object.

Click on Texts, Images, Frames, and Prezi will zoom you to them. Prezi will automatically zoom, pan, rotate, to the object so it appears centered and readable on screen. 

Zoom out.

Clicking on the background starts smart zoom out. This means that prezi will look for the next largest enclosing Frame, then zoom and rotate up to it. If there are no more enclosing Frames, it will zoom to the overview.

Zoom in/out around the center of the screen.

REMEMBER: When in show mode the zoom menu will dissapear to give you a clear presenting screen. To bring it back hover your mouse over the right edge of the screen.
