Temporary Extension Lines

Temporary extension lines are vertical and horizontal lines through the point, which was last touched with the cursor. The extension line appears on the screen whenever the cursor is moved vertically or horizontally after touching a point. On the extension line any point can be snapped now.
If the -key is depressed when touching a point, the system remembers the point and ignores other ones until the key is released.
