setMagicCaretPosition</H3>
<PRE>
public void <B>setMagicCaretPosition</B>(<A HREF="../../../java/awt/Point.html">Point</A>&nbsp;p)</PRE>
<DL>
<DD>Set the current caret visual location.  This can be used when 
 moving between lines that have uneven end positions (such as
 when caret up or down actions occur).  If text flows
 left-to-right or right-to-left the x-coordinate will indicate
 the desired navigation location for vertical movement.  If
 the text flow is top-to-bottom, the y-coordinate will indicate
 the desired navigation location for horizontal movement.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>p</CODE> - the Point to use for the saved position.  This
   can be null to indicate there is no visual location.</DL>

setBlinkRate</H3>
<PRE>
public void <B>setBlinkRate</B>(int&nbsp;rate)</PRE>
<DL>
<DD>Sets the blink rate of the caret.  This determines if
 and how fast the caret blinks, commonly used as one
 way to attract attention to the caret.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>rate</CODE> - the delay in milliseconds >= 0.  If this is
  zero the caret will not blink.</DL>
</DD>
</DL>
<HR>

<A NAME="getBlinkRate()"><!-- --></A><H3>
getBlinkRate</H3>
<PRE>
public int <B>getBlinkRate</B>()</PRE>
<DL>
<DD>Gets the blink rate of the caret.  This determines if

</DD>
</DL>
<HR>

<A NAME="getMark()"><!-- --></A><H3>
getMark</H3>
<PRE>
public int <B>getMark</B>()</PRE>
<DL>
<DD>Fetches the current position of the mark.  If there

 the dot.<DD><DL>
<DT><B>Returns:</B><DD>the position >= 0</DL>
</DD>
</DL>
<HR>

<A NAME="setDot(int)"><!-- --></A><H3>
setDot</H3>
<PRE>
public void <B>setDot</B>(int&nbsp;dot)</PRE>
<DL>
<DD>Sets the caret position to some position.  This
 causes the mark to become the same as the dot,
 effectively setting the selection range to zero.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>dot</CODE> - the new position to set the caret to >= 0</DL>
</DD>
</DL>
<HR>

<A NAME="moveDot(int)"><!-- --></A><H3>
moveDot</H3>
<PRE>
public void <B>moveDot</B>(int&nbsp;dot)</PRE>
<DL>
<DD>Moves the caret position (dot) to some other position,
 leaving behind the mark.  This is useful for
 making selections.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>dot</CODE> - the new position to move the caret to >= 0</DL>
