Table: this command displays the attribute Table of a selected vector layer.

Find: this command select entities by entered keywords. Separate keywords by space! Each keyword must occur within the attributes to select it. The Record panel on the right side shows the selected records.

Point: this tool select entities around the designated point. The Records panel on the right side shows the selected records.

Line: this tool adds vertices to the input geometry. During vertex input the lenght of the polyline is displayed on the map, so this tool can be used for length measurements. Pressing the Query button selects entities under the polyline or in close proximity of the polyline. The Record panel on the right side will show the selected records.

Area: this tool adds vertices to the input geometry. During vertex input the area of the polygon is displayed on the map, so this tool can be used for area measurements. Pressing the Query button selects entities under the polygon. The Records panel on the right side will show the selected records.

Query: this command terminates the vertex collection of the previous two tools and graphically selects entities by the input geometry. The Records panel on the right side will show the selected records.

New part: this command adds a new part to the input geometry constructing a multipart geometry (multi polyline, islands or holes in a polygon).

Back: this command deletes the last vertex of the input geometry.

Restart: this command erases all vertices of the input geometry.
