Answer 1

That's Zoomit

ZoomIt is a screen zoom and annotation tool for technical presentations that include application demonstrations. ZoomIt runs unobtrusively in the tray and activates with customizable hotkeys to zoom in on an area of the screen, move around while zoomed, and draw on the zoomed image. I wrote ZoomIt to fit my specific needs and use it in all my presentations.

ZoomIt works on all versions of Windows and you can use pen input for ZoomIt drawing on tablet PCs.

Great tool.
