+
+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:
+
+\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}
+
+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 projections are also supported.
