Only after the presentation did I get a chance to see if there was a zoom feature. It turns out that there is and it's embarrassingly obvious now. It was pretty much where you would think it would be, in the bottom left corner, displaying "100%".
There are other ways to use the zoom feature and if you're using a mouse than holding down the ctrl key and scrolling the mouse wheel will zoom in and out nicely. There are also keyboard shortcuts, which are by default set to Ctrl+Shift+Comma to zoom out and Ctrl+Shift+Period to zoom in. These of course can be modified to use different short cut keys by going to Tools>Options>Keyboard and selecting View.ZoomIn and View.ZoomOut commands.
This is great, but as it turns out it still wouldn't have solved all of our problems during the presentation. The presenter wanted to show the solution explorer in VS 2010 and explain the folder layout of a typical MVC project. However, the VS 2010 zoom feature only works on the text in the code editor window. We needed something that can zoom in on our entire window and it turns out that there are numerous applications that can do this. But the one that I like is called ZoomIt. And it's made by Mark Russinovich, so you know its going to be good. As stated on the introduction page of the application page he "wrote ZoomIt to fit my specific needs and use it in all my presentations." So the next time you need to give a presentation make sure you're Ready.. Set.. Zoom!
