-The wxGUI vector digitizer draws all maps in the Layer Manager in the Map 
-Display window; in addition, the digitizer also recognizes a special 
-"background" vector map. This map is selected from the Layer Manager by 
-right-clicking on the map and selecting "Use as Background Map" from the
-contextual menu. The features of the background map may then be copied into
-the currently edited vector map using the "Copy features from (background) 
-vector map" button in the "Additional Tools" menu on the Digitzer Toolbar.
+Vector digitizer allows to define "background" vector map. A
+background map can be selected from map layer contextual menu in Layer

+features are snapped in the given threshold to the features from the
+background map. Vector features may be also copied from the background
+map by "Copy features from (background) vector map" tool
