On-Air is OnCue's version of a mirror mode that will automatically update what's on the presentation screen with what you click on in the documents pane.

You never want to show the behind the curtain when using OnCue, you only want to show the Presentation Screen. OnCue has a few ways you can do this. You can use just the extended desktop or if you do not have real estate for a second monitor, use On-Air.

Press the Annotate/Present button in your Workflow Ribbon. This will bring up the Viewer.

	In the left-hand corner, you will see an icon that says "OFF AIR"
	Select a document and then press that button to go "ON AIR"

The default hotkey to toggle On-Air on/off is ALT + M.

If ON-AIR is toggled on, whatever is showing in your Viewer is immediately published and everything you do in the Viewer is duplicated in Presentation, with the exception of your mouse cursor. No functionality is lost when you are presenting in ON-AIR, you can still use X + <ID> and other commands.

Also, in the top right corner of your Production screen there is a helpful indicator to let you know which screen has focus for hotkey commands.

Want to leave the document up in Presentation but not continue to use On-Air? You can toggle it off and on it will continue to show on your presentation screen. 

PRO TIP: if you have a document up in Presentation and have navigated away from it in Production, just hit Alt + F5 (Reverse Publish) – any doc on the Presentation screen is put back on your Viewer.
