Input with Mouse Buttons

• The left mouse button is used to enter two-dimensional points (x- and y-coordinates). The corresponding height (z-coordinate) for the specific input is taken from the appropriate parameter settings.

• Rectangular areas are entered by clicking with the left mouse button two opposite corners in any order.

• A set of points, e.g., as required for trajectories, polygons or lists, is entered by consecutive left mouse button clicks.

• The right mouse button is used either to abort input or to finish input.

• An input can always be aborted before the first point is entered pressing the right mouse button. In some cases--for instance, while entering a rectangular area--the input can be aborted after the first point has been entered already.

• Multi-point input, e.g., entering a trajectory or list, is finished with a right mouse button click.
