Selection tool

The Selection tool can be found on the Toolbar. It's used to select, scale, rotate, and move drawings. Using this tool, it's possible to apply changes to all lines and/or areas in that selection.

Tool Options
Tool options can be enabled in Windows >Tool Option Bar, or by right-clicking and selecting GUI Show/Hide >Tool Options Bar.

Type
This allows you to choose the method of selection: Rectangle, Freehand (similar to the Lasso tool in other programs), and Polyline.

Mode
This controls which part of the drawing and level can be selected.

Unique controls

 * You may notice a small icon to the bottom left of your selection. This controls the line thickness. Clicking on the icon and dragging upwards increases the thickness, while dragging downward decreases it.
 * Holding down CTRL while dragging a node will skew the selection.
 * Holding down SHIFT while dragging will lock the ratio of height to width, ensuring the selection scales uniformly.
