-For both PostgreSQL/PostGIS and shapefile-based layers, the vertices of
-features can be edited.
+For both PostgreSQL/PostGIS and shapefile-based layers, the
+\toolbtntwo{mActionNodeTool}{Node Tool} provides manipulation capabilites
+of feature vertices similar to CAD programs. It is possible to simply select
+multiple vertices at once and to move, add or delete them alltogether. The node
+tool also works with 'on the fly' projection turned on and supports
+the topological editing feature. This tool is, unlike other tools in Quantum GIS,
+persistent, so when some operation is done, selection stays active for this
+feature and tool.
-Vertices can be directly edited, that is, you don't have to choose which
-feature to edit before you can change its geometry.
-In some cases, several features may share the same vertex
-and so the following rules apply when the mouse is pressed
-down near map features:
-
-\begin{itemize}
-\item \textbf{Lines} - The nearest line to the mouse position
- is used as the target feature.
- Then (for moving and deleting a vertex)
- the nearest vertex
- on that line is the editing target.
-
-\item \textbf{Polygons} - If the mouse is inside a polygon, then it is
- the target feature; otherwise the nearest polygon
- is used.
- Then (for moving and deleting a vertex)
- the nearest vertex
- on that polygon is the editing target.

\end{Tip}
-In this version of QGIS, vertices can only be added to an \textit{existing}
-line segment of a line feature. If you want to extend a line beyond its end,
-you will need to move the terminating vertex first, then add a new vertex where
-the terminus used to be.
+\minisec{Basic operations}\index{vector layers!Node Tool}
-With the \toolbtntwo{mActionMoveVertex}{Move Vertex} icon on the toolbar you
-can move vertices.\index{vector layers!moving!vertex}
+Start by activating the \toolbtntwo{mActionNodeTool}{Node Tool} and selecting
+some features by clicking on it. Red boxes appear at each vertex of this feature.
+This is basic select of the feature. Functionalities are:
-With the \toolbtntwo{mActionDeleteVertex}{Delete Vertex} icon on the toolbar
-you can delete vertices.\index{vector layers!deleting!vertex} Please note, it
-doesn't make sense to delete the vertex of a Point feature! Delete the whole
-feature instead.
+\begin{itemize}
+\item \textbf{Selecting vertex}: Selecting is easy just click on vertex and
+color of this vertex will change to blue. When selecting more vertices
+\keystroke{Shift} key can be used to select more vertices. Or also the
+\keystroke{Ctrl} key can be used to invert selection of vertices (if selected then
+it will be unselected and when not selected vertex will be selected). Also more
+vertices can be selected at once when clicking somewhere outside feature and opening a rectangle where all vertices inside will be selected. Or just click on an edge and
+both adjacent vertices should be selected.
+\item \textbf{Adding vertex}: Adding vertex is simple, too. Just double click near
+some edge and a new vertex will appear on the edge near to the cursor. Note that
+vertex will appear on edge not on cursor position, there it has to be moved if
+necessary.
+\item \textbf{Deleting vertex}: After selecting vertices for deletion, click the
+\keystroke{Delete} key and vertices will be deleted. Note that according to
+standard Quantum GIS behavior, it will leave a necessary number of vertices for
+the feature type you are working on. To delete a complete feature, another tool
+has to be used.
+\item \textbf{Moving vertex}: Select all vertices you want to move. All selected
+vertices are moving in the same direction as the cursor. If snapping is enabled,
+the whole selection can jump to the nearest vertex or line.
+\end{itemize}
-Similarly, a one-vertex line or a two-vertex polygon is also fairly useless
-and will lead to unpredictable results elsewhere in QGIS, so don't do that.
+The \button{Release} button stores all changes and a new entry appears in the undo
+dialog. Remember that all operations support topological editing when turned on. On
+the fly projection is also supported.
-\textbf{Warning:} A vertex is identified for deletion as soon as you click
-the mouse near an eligible feature.
