====== Rectangular selection ======


===== Icon ===== 
{{:icon:rectangular_selection.png?50|}}

===== How it works =====

**Only available in expert mode**.

This option allows you to select a set of points for modification using another option (delete, move to another map...).

This option is only available **when at least one project is loaded into the application**.

===== Application =====
Once the icon has been triggered, the option works in several stages:
  * The first left-click on the map draws the first corner of the selection window.
  * As long as the click is maintained, the mouse draws the selection window to the opposite corner.
  * When the click is released, the selection is validated and all points inside the window are highlighted with a blue filter.

Once this filter has appeared, it is possible to use the options using these selected points:
  * [[delete|Deleting points]]
  * [[delete_area|Deletion with intersection]]
  * [[split|Separating points in a new map]]
  * [[add_missing_points|Adding missing points]]
