Arrows

To draw a basic arrow, click on the arrow tool in the tools palette and the various options for arrows will be loaded in the inspector palette.  Draw out an arrow on your canvas.  

Arrowhead Size:  The arrowhead can be increased or decreased in size by clicking and dragging on the point at the base of the head. 

Arrow Length:  The length of the arrow can be increased or decreased by clicking and dragging on the points at the tip of the tail or the head. 

To learn more about fill, stroke, and shape rotation, read the 'shape tools' tutorial.

Modifying the Arrow Tail and Arrow Width

In order to modify the shape of the arrow tail, choose Shape ▸ Bézier Stuff ▸ Convert to Bézier Shape.  Then, click and hold on the bézier tool in the tools palette until a drop down menu appears.  Choose 'Bézier Anchor Select Tool'.  Click and drag on one of the bézier points of the arrow tail to modify its appearance.

To modify the width of the arrow, choose Shape ▸ Bézier Stuff ▸ Convert to Bézier Shape (if you haven't already).  Select the move tool and click and drag on an edge of the bounding box. 

Note: Converting your arrow to a bézier shape is a permanent operation unless you chose Edit ▸ Undo.

Stars

The star shape tool defaults to a 5 point star when you initially draw it on your canvas.  All of the standard shape tool options are available for the star in the inspector palette.

You can increase or decrease the internal star radius by clicking and dragging on the inner circle of the on canvas controls.  You can also quickly resize, increase or decrease star points, and rotate your star shape by using the on canvas controls.
