To constrain movement to one axis only, drag the arrowhead at the end of the desired axis. This saves
you from having to lock axes manually.
You can also lock the movement to an axis by double-clicking the arrowhead for that axis, which will
then turn yellow. You can then drag from any position in the viewport to move the object along the
locked axis (you no longer need to drag the arrowhead itself). To change which axis is locked, click
one of the other axis arrowheads. To unlock the axis, double-click its arrowhead or one of the other
axis arrowheads.
To move the selected object without its children, Ctrl-drag the object in the viewport.
To constrain (i.e. lock) the movement to a plane, such as the XY plane, hold down Shift and drag the
arrowhead for that axis (in this case, drag the Z-axis arrowhead). Release the Shift key once you have
started to drag, otherwise the object/element will snap to the grid.
When editing textures, mouse movements have a somewhat different effect. A left/right drag of the
mouse moves the texture along its X-axis, an up/down drag moves the texture along its Y-axis.
Moving multiple objects
When multiple objects are selected, a shared axis system appears in the viewport between the selected
objects. You can move the objects using the shared axis system or you can move the objects using any
one of their object axis systems (click the origin of the object axis system that you want to use).
When multiple objects are selected,
a shared axis system appears in the
center.
Click the origin of the object whose axis
system you want to use; this object’s
axis system then appears.
