Mit einem „Griff“ können bestimmte Parameter eines Layers verändert werden. So wird z. B. ein Kreis einen Griff, der die Position des Mittelpunktes festlegt, und einen Griff, der den Radius des Kreises bestimmt, haben.

In dem Bearbeitungsfenster werden für alle selektierten Layer und für alle selektierten ValueNodes Griffe angezeigt. Wenn unerwarteterweise Griffe sichtbar sind, kann es sein, dass in der Kinderanzeige noch ein ValueNode selektiert ist.

Drag the ducks around to change the parameters. Hold shift while dragging to constrain the movement to be either horizontal or vertical.

More precise control of the ducks can be achieved using the cursor keys. The cursor keys will move the currently selected duck one pixel at a time, or ten pixels at a time if the shift key is pressed.

More than one duck can be selected at a time. Hold control while clicking on a duck to toggle the selection on and off without affecting the selection status of the other ducks. Drag a rectangle around a group of ducks to select them all and unselect the other ducks. Hold control while dragging a rectangle around a group of ducks to select them as well as the currently selected ducks. Hit control-A to select all non-position ducks.

Why 'ducks'? According to Philip J. Schneider:

Back in the days before computers, architects, engineers, and artists would draw their designs for buildings, roads, machine parts, and the like by using pencil, paper, and various drafting tools. These tools included rulers and T-squares for drawing straight lines, compasses for drawing circles and circular arcs, and triangles and protractors for making precise angles.

Of course, a lot of interesting-shaped objects couldn't be drawn with just these simple tools, because they had curved parts that weren't just circles or ellipses. Often, a curve was needed that went smoothly through a number of predetermined points. This problem was particularly acute in shipbuilding: although a skilled artist or draftsman could reliably hand-draw such curves on a drafting table, shipbuilders often needed to make life-size (or nearly life-size) drawings, where the sheer size of the required curves made hand drawing impossible. Because of their great size, such drawings were often done in the loft area of a large building, by a specialist known as a loftsman. To aid in the task, the loftsman would employ long, thin, flexible strips of wood, plastic, or metal, called splines. The splines were held in place with lead weights, called ducks because of their resemblance to the feathered creature of the same name.

Also, according to wikipedia:

Before computers were used for creating engineering designs, drafting tools were employed by designers drawing by hand. To draw curves, especially for shipbuilding, draftsmen often used long, thin, flexible strips of wood, plastic, or metal called a spline (or a lath, not to be confused with lathe). The splines were held in place with lead weights (called ducks because of their duck like shape).
