There are also four automatic modifications you can have AutoSketch make to the point you enter. These "lock modifiers" force the point you enter into horizontal, vertical, orthogonal, or "normal" alignment with the last point. You can choose a lock modifier at any time in the drawing or editing process by clicking its button on the All-In-One toolbar or by typing the letter shown on the button. Snap and lock commands are also located on their own toolbars, which contain the same commands as the toolsets but can be docked anywhere onscreen. When snaps involving the mouse are active, a red AutoPoint Indicator appears. As you move the pointer over the drawing, each type of snap point is represented by a different symbol: squares for endpoints, triangles for midpoints, circles for centerpoints, and so on. If a lock modifier is active as well, a dotted line extends from the AutoPoint Indicator to the actual point, as constrained by the lock modifier. For instance, if you draw a diagonal line from top to bottom, then activate Endpoint snap and the Y-axis lock modifier, the square AutoPoint Indicator identifies the endpoint nearest the pointer, but a dotted line extends to the potential snap point based on the current snap and lock modifier.
