<p class="Paragraph">This function is only available if a corresponding object has been selected in your document. Here it may be a case of <help:switch select="Program" xmlns:help="http://openoffice.org/2000/help"><help:case select="WRITER">a border, </help:case></help:switch>a graphic, a draw object, a control or another inserted object such as an OLE object or a chart.</p>
<p class="Paragraph">Imagine that your pages are composed of three transparent layers: the text layer, the graphic layer in the foreground and a graphic layer in the background. These layers rest directly on top of each other, one containing text and the others the graphics. All graphic objects in the graphic layer lie on top of each other, the first element at the bottom, and subsequent objects on top; whereby the bottom elements are overlapped or hidden by other objects. Each new graphic element first appears in the graphic layer in the foreground, covering the text layer.</p>
<p class="Paragraph">Form controls have an additional controls layer. Controls are located only in the controls layer. They are always drawn last, and are optically above all other objects and text on the page. Yet, object selection is still based on the internal object sequence. For example, if you draw a control first, then a rectangle that partially covers the control and click a part of the screen where both objects are, the rectangle will always be selected.</p>

<p class="Paragraph">The order of the graphic objects within the graphic layer can be modified using the first four submenu commands, while the last two commands arrange the selected objects behind or in front of the text layer.</p>
