<p class="Paragraph">If you hold the Shift key down, the movement of the mouse is limited to multiples of 45 degrees. If you hold down the <help:switch select="System" xmlns:help="http://openoffice.org/2000/help"><help:case select="MAC">Options</help:case><help:default>Alt</help:default></help:switch> key, the new point will not be connected to the last point. This allows you to create objects that consist of curves that are not connected together. If you draw a smaller object while holding down the <help:switch select="System" xmlns:help="http://openoffice.org/2000/help"><help:case select="MAC">Options</help:case><help:default>Alt</help:default></help:switch> key into a larger object that you have not closed yet, the smaller object is subtracted from the larger one, thus appearing as a hole in the larger one.</p>
