If the template needs editing (adjusting the position of a point), it can be done in the secondary view when the option "Edit points" is enabled. Maintaining the "CTRL" key pressed and selecting one or many points will move them if you drag the mouse with a left-click. The points selected will be highlighted in yellow. Once the position of the point is adequate, release the "CTRL" key.
Template points can also be selected by clicking the 
icon on the top left of the section and creating the selection window with the mouse. All points within the window will be selected.
If a line is selected instead of a point with the "CTRL" key pressed, the entire template and all its points will be highlighted. The whole template can then be displaced.
Furthermore, the secondary view cannot be rotated when editing points. If the window had been rotated before the “Edit points” function is triggered, it can be reinitialized perpendicularly to the alignment by clicking 
at the top left of the secondary window.
