Objects
Use the tools on the main toolbar to add shapes to your documents. You can tear off the palettes and place them
where you want. You can rotate an object using its rotation handle and scale or distort an object by using the resize or
distortion handles.
Arrows
You can use arrows to show the conversion of reactants to products and to indicate electron flow. You can customize
arrows not only for length and angle, but for arrowhead width and shape. You can also drag an arrow from its middle to
create an arc of any length. When you create an arc, the angle of the arrow is modified.
When you mouse-over an arrow with the Lasso, Marquee, or an Arrow tool selected, the adjustment handles appear.
Drag the adjustment handles to change the arrow length, angle, or shape. When changing the angle of an arrow, you
are restricted to multiples of 15° if Fixed Angles is selected. Hold down the ALT key to drag to any angle. You can
also create an arrow by drawing an arbitrary spline using the pen tools, and then adding an arrow head.
Arrow heads
There are three arrow head shapes, solid, hollow, and angled. To change the shape, right-click an arrow and choose
the shape from the context menu.
Arrow heads; A) Solid arrow head; B) Hollow head; C) Angled head.
