Most probably one menuitem returns the command for a single intersection point (single_inter), the other one a list of intersection points (inter).

Sorry, but when i construct to lines with one intersection point, an choose "Point -> Intersection" and choose one after another line then it constructs no intersection point . Where i have made an mistake? Can you describe me the procedure (not mentioned in manual).

When i construct the midpoint C between to points A and B then the "Enter"-key normally show me the list of points for choosing. But in this list there are only the point A and B. But not the point C. Why?
