Text Move

The Text Move command allows a text entity to be moved by specifying a new origin location.

The text entity to be moved is selected, followed by the selection of a new point location for positioning the origin of the selected text entity. If the appropriate defaults drag option is active, the selected text entity will appear dynamically moving with the cursor movements. Its origin is at the crosshairs of the cursor, thereby assisting accurate locating of the new origin location. New origin locations can be continually selected and the text entity will be temporarily moved to it. The actual move is executed by aborting further selection of point locations with the abort button. The selected text entity will be moved and its new origin location will be the last point location selected.
