Keynote gives you the ability to control your presentation from an iPhone or an iPad. This allows you, as the presenter, the chance to move around and not have to stand beside your computer.
Your notes from your Keynote will be available to you on your iPad. You can tap the screen or swipe from the right to the left to advance your slide or you can swipe from the left to the right to go back to the previous slide.
To connect your iPad to your computer, they both need to have Keynote open and be connected to the same wifi network. The tutorial video below shows the screens side by side in real time and will help you connect Keynote on your iPad to Keynote on your computer.

Another fantastic feature of controlling your Keynote from your iPad is the ability to draw on the slides.
