+The Command widget is an area, often rectangular, that contains text
+or a graphical image. Command widgets are often referred to as
+``push buttons.'' When the pointer is over a Command widget, the
+widget becomes highlighted by drawing a rectangle around its perimeter.
+This highlighting indicates that the widget is ready for selection.
+When mouse button 1 is pressed, the Command widget indicates that
+it has been selected by reversing its foreground and background colors.
+When the mouse button is released, the Command widget's <function>notify</function>
+action is invoked, calling all functions on its callback list. If
+the pointer is moved off of the widget before the pointer button is
+released, the widget reverts to its normal foreground and background
+colors, and releasing the pointer button has no effect. This behavior
+allows the user to cancel an action.
