Presentation Mode
Presentation mode is available from the View menu; it fills the entire screen with your document so that you can easily present it to others.
Each canvas acts as a slide; use the arrow keys to move between canvases. You can also press Return or Enter, or click, to move to the next canvas. If your Presentation preferences are set to highlight an object when you click it, doing so won't advance to the next canvas; you can still click an empty area of the canvas to advance.
You can highlight objects to draw attention to them during the presentation. Use the Presentation preferences to control how highlighting happens.
Press Escape, or advance past the final canvas, to leave presentation mode.
Actions set up in the Properties: Action inspector work while in presentation mode. When you click an object that has an action assigned, it performs the action as if you had clicked it with the Browse tool.
If you have more than one window open, the frontmost window is used for the presentation. If you have two displays, you can put the presentation on one screen while editing the document on the other.
Drag one window to the second display.
Click the window on the second display to make sure it is frontmost.
Enter presentation mode. The second display shows the presentation while your first display keeps its normal document window.
Now you can edit the document on the first display and the presentation on the second display updates itself.
