Snapping

Snapping helps you to align widgets precisely. Widgets within the 'snapping distance' are pulled towards helper lines and the edges of other objects and automatically aligned with them.

To turn snapping on or off:

Click Settings.
Select or clear the Snapping check box to toggle snapping on or off.

Note: To temporarily toggle helper lines and snapping or off, press the S key while dragging a widget. While the S key is pressed, a message indicates whether snapping is on or off.
