Did you know that you can drag 2D geometry so as enpoints of the geometry snap other existing geometry. Fir Instance, picking a line and then drag to to other geometry which let you use the endpoint of the line closest to where you selected the line be the "snap" point to other geometry. Drag the line so that its endpoint moves over another endpoint and see how the lines endpoint automatically snaps to it (large dreen dot appears). But if you drag the line so as the other endpoint (farthest from you selected point) moves over other points WILL NOT snap. To do that simply select the line closest to that endpoint.
Kind of hard to describe, so I have attached a quick viewlet showing this.
