Removing features, unlike removing layers and types of a theme described in chapter 12 “Themes”, does not cause only changing of map displaying method, but actual change of map contents. Removed features do not longer exist on the map.
To remove one feature or several features at once they should be selected first (using any method).
The menu command Selection+Remove performs removing of all selected features. Since removing destroys all the information about features, the system asks for confirmation of the operation informing about the number of selected features subject to removing.
Pressing the key Delete produces the same effect as the command Selection+Remove.
If the system is in the mode of interactive editing of features, it is possible to use the context menu command Delete to remove the selected feature or group of features. Unlike the method described above, in the mode of editing the system does not ask to confirm the operation of removing.
The key Delete can be also used to remove the features being edited, however, in the submode of editing vertices it does not cause removing of the whole feature, but only of the selected vertices of the feature.
