When a raster area is selected, pixels within the selection can be moved, resized, or rotated using the mouse.
For example, pixels that represent a depth contour are selected using the Select Raster by Rectangle tool.
While in selection mode, pixels can be moved using the mouse to drag the selection to a new location.
Selections can also be resized or rotated using handles.
While in selection mode, the pointer changes shape to the edit mode available. The following table shows pointer icons and associated editing operations
