Selection Tool Steps

1. Click the tool button to activate the selection tool.
2. For polygon tools, click the left mouse button to define the vertices of the polygon in the area of interest. The program will automatically form a closed polygon. Double-click to finish. For other selection tools, click the first point, drag the mouse to cover the area of interest, and double-click to complete the selection.
3. If vertices are misplaced in the polygon selection, right-click to cancel the last selected vertex. This operation can be performed multiple times.
4. Double-click the left mouse button on the last vertex to end vertex selection. The points within the selected polygon area will be highlighted (in red).
5. After completing one selection, you can perform another selection based on the first. Cancelling the result of the last clipping will also cancel the clipping of the corresponding selection area.
6. Each selection area will either add to or subtract from the existing selection area based on the inverse selection state.
