I've been putting the finishing touches on a TFS 2008 presentation that I'll be giving at this year's Tulsa TechFest conference later this month and came across a utility that promises to be extremely useful. It's called NLarge and provides the ability to zoom in and out of a presentation (or any other displayed materials) using a smooth scrolling effect. NLarge runs in the taskbar notification area and can be activated with a hotkey (Alt+1). Once activated, the zoom feature can be controlled with the mouse, tablet pen, and/or keyboard. Although I haven't used this utility during a presentation yet, I think it will be extremely valuable in aiding those in the back of the room to see what I'm focusing on.
