For example, I would like to be able to snap to an imaginary point halfway between two keypoints. This imaginary point may be a point in space between one corner of a block or rectangle and another one.
With AccuDraw active, if you push the space bar it switches Accudraw from an X,Y,Z (or just X,Y in 2d) format to a "Distance, Angle" format. With it set to Distance and Angle just snap to the first point, key in "O" to set the Accudraw Origin, then snap to the second point and key in your divisor ie /2.
