The width of the pen stroke can be varied. You can draw rectangles, ellipses and straight lines by holding a key down as you go. There's blanket erase (with one keystroke) and incremental undo, but no redo. With one keystroke, you can turn the entire display into a whiteboard or blackboard. You can copy the screen (to be pasted into an appropriate program) or save it to disk (as an image).
Three caveats: if you switch among screen annotation, whiteboard and blackboard you lose your annotations there is no way to return to presentation mode, then come back and retain your annotations and the image capture is always the full screen (so you may need to crop in another program before uploading it to its final home). Image manipulations can be done in a variety of programs (I recommend IrfanView).
