 <para>Clicking with the &LMB; on the &kruler; will turn the cursor to a cross
 with four arrows and enables you to drag &kruler; around the screen.</para>
 
 <para>When you move the mouse over &kruler;, your cursor will turn into a
 red arrow.  As you move the cursor, &kruler; will
 display how far from the origin the cursor currently is.
 </para>
 
 <para>You can resize the ruler by moving the mouse over the handle on the
 left or right edges of &kruler; (the top or bottom edges when it is oriented
 vertically), holding down the &LMB; and dragging the handle.</para>
 
 <para>You can change the orientation in two different ways:</para>
 
 <simplelist>
 <member>Clicking the &MMB; switches the ruler from vertical to horizontal orientation</member>
 <member>Using the context menu, described in the next chapter</member>
