To move a selected unit (or units) around in the display, hold down the left mouse button after the last selection. The mouse cursor will change from the normal pointer to a crosshair. Move the mouse pointer to the desired location and release the left button. The unit (or units) will be moved relative to the mouse drag.

Adding Related Units

To add units related to a selected unit (or units), choose one of the "add" actions from the action menu. Any units related to the selected unit (or units) by the chosen relationship will be added. The following relationships can be chosen:

The grid layout arranges units in rows and columns (in no particular order). The ellipse layout arranges units around an ellipse (in no particular order).
