How to finish Polygonal Area

Hi,
seems like LibreCAD is a powerfull tool.
But how can I use Measurment of Polygonal Area?
This is how to tell the system that a point is the last point and I want the result?
Definitely a point which belongs into the user manual, but which I could not find there.

in 1.0.0RC* versions:

Left click to add corner to polygon which is used to calculate area. Choose the first corner to close the polygon and do calculation.

Right click to do the calculation, if a polygon is formed (by 3 or more corners).

In master branch:

Left click to add corner to polygon, when 3 or more corners added, calculation of the polygon is auto.

Right click to cancel

Please report a bug, if you still have trouble to get polygon area

Finding area defined by closed entities is on todo list, and is closely related to hatch improvement
