I know, I said that about the SQL Internals Viewer, and that of course was amazing, but very limited in scope.
I just found Zoomit at http://technet.microsoft.com/en-us/sysinternals/bb897434.aspx#
This is the tool I have been hoping to find for years and years of teaching classes and presenting conference sessions. And it was written by Mark Russinovich, of SysInternals fame... so you know you can trust it.
It's small, it's easy, it does just what I want as a presenter, but not a whole lot more.
A quick hotkey, and I can magnify an area of my screen... I can zoom in and out with my mouse wheel. This is great to show menus in Management Studio.
Another hotkey and I can draw on the screen, change the width of the line and the color.
One more hotkey, and I can WRITE TEXT on the screen! This is so way cool...I'm supposed to be prepping for a presentation tomorrow, it is almost midnight, and all I want to do is draw all over my screen with Zoomit.
Oh, and there is also a timer function for letting students know when to come back from breaks!
THANK YOU MARK!!!
