  <listitem>
<para>Specifies a mouse binding definition. <emphasis remap='I'>button</emphasis> is the mouse button
number [0, 1, 2, or 3]. If <emphasis remap='I'>button</emphasis> is zero, then any mouse button
invoked issues the <emphasis remap='I'>Command</emphasis>.  <emphasis remap='I'>context</emphasis> describes where the
mouse click occurred and can be any combination of the following:</para>

<literallayout remap='.nf'>
   R = Root window (main background)
   F = Window Frame (the BottomBar handle corners)
   S = Window TitleBar or BottomBar
   I = Iconified Button (minimized window icon)
   T = Window TitleBar
   W = Application Window
   A = Any of the above except for TitleButtons
1-10 = TitleButton number of the TitleBar, corresponds to the
       entry in the <emphasis remap='I'>look.name</emphasis> file
</literallayout> <!-- .fi -->

<para>The action to be taken by the defined TitleButton is defined in the
<emphasis remap='I'>feel.name</emphasis> file.  Defining a TitleButton without having a corresponding
entry in the <emphasis remap='I'>feel.name</emphasis> file will cause the TitleButton icon to be
displayed, but not react when pressed.</para>

<para><emphasis remap='I'>modifier</emphasis> is the key-stroke combination associated with the
<emphasis remap='I'>context</emphasis> entry, to issue the <emphasis remap='I'>Command</emphasis>. Valid <emphasis remap='I'>modifier</emphasis>'s
are:</para>

<literallayout remap='.nf'>
   N = No modifiers
   C = Control
   S = Shift
   M = Meta
   A = Any modifier
</literallayout> <!-- .fi -->

<para><emphasis remap='I'>Command</emphasis> can be any <command>afterstep</command> <emphasis remap='I'>Built-in</emphasis> command/
function, <emphasis remap='I'>Popup</emphasis> or user defined <emphasis remap='I'>Function</emphasis>.</para>
