This command draws a white solid rectangle to highlight the
selected text. The display order for the solid is set behind the
text and the solid is drawn on the current layer. This command is
only useful when the text itself is not white. At the command
prompt, type O for Options to bring up the settings dialog for how
to set the layer for the solid.
