Solid Edge has a set of shortcuts for point location within a sketch. MICE stands for midpoint, intersection, center and end. While drawing a line (or other sketch elements),you can hover your mouse near the end of a line segment, edge, arc, etc. and hit the E key and it will automatically start the line at the closest end point of the element you're hovering over. Or you can hover over a circle/arc and hit C and the line segment will start at the center of the circle. It speeds up sketching by allowing you not to have to hunt for points as much.

Does SW have anything like this? It's extremely useful.
