Once items are added to a form, you can change their size by either
re-sizing or expanding them.
Re-sizing items
Items in the Palette have a default size. You can re-size items once they are in the form by either nudging items or dragging their edges.
Expanding items
You can simultaneously resize and align items by expanding them. This is a quick way to resize items so that they line up with other items exactly. Expanding can either be done relatively, or absolutely.
