This format will add a raised grey bar effect to any tool bar (created using %bt (Button), %ib (Image Button), %tt (Textual Toolbar), or %tb (Bitmap Button)) set at the top of the window. It takes one floating point argument that specifies the additional depth (in average characters) to be inserted above and below the bar.
