<DL>
<DD>Return a shared instance of a key stroke, given a character object
 and a set of modifiers. Note that the first
 parameter is of type Character rather
 than char. This is to avoid clashes with code that existed prior
 to the introduction of this method, which may have been calling
 getKeyStroke(int keyCode, int modifiers) with quoted characters
 and relying on their automatic conversion to type int.

 The modifiers consist of any combination of:<ul>
 <li>java.awt.Event.SHIFT_MASK (1)
 <li>java.awt.Event.CTRL_MASK (2)
 <li>java.awt.Event.META_MASK (4)
 <li>java.awt.Event.ALT_MASK (8)
 </ul>
 Since these numbers are all different powers of two, any combination of
 them is an integer in which each bit represents a different
 modifier key.<DD><DL>

<DL>
<DD>Return a shared instance of a key stroke given a numeric keycode and a set
 of modifiers, specifying whether the key is activated when it is pressed
 or released.
 <p>
 The "virtual key" constants defined in java.awt.event.KeyEvent can be 
 used to specify the key code. For example:<ul>
 <li>java.awt.event.KeyEvent.VK_ENTER 
 <li>java.awt.event.KeyEvent.VK_TAB
 <li>java.awt.event.KeyEvent.VK_SPACE
 </ul>
 The modifiers consist of any combination of:<ul>

<DL>
<DD>Return a keystroke from an event.

 This method obtains the keyChar from a KeyTyped event,
 and the keyCode from a KeyPressed or KeyReleased event,
 so you the type of event doesn't matter.<DD><DL>

<DL>
<DD>Parse a string and return a KeyStroke.
 The string has the following syntax:
 <pre>
    &lt;modifiers&gt;* (&lt;typedID&gt; | &lt;pressedReleasedID&gt;)
    modifiers := shift | control | meta | alt | button1 | button2 | button3
    typedID := typed &lt;typedKey&gt;
    typedKey := string of length 1 giving unicode character.
    pressedReleasedID := (pressed | released)? key
 key := KeyEvent keycode name, i.e. the name following "VK_".
 </pre>
 If typed, pressed or released is not specified, pressed is assumed.
 Here are some examples:
 <pre>
     "INSERT" => new KeyStroke(0, KeyEvent.VK_INSERT);
     "control DELETE" => new KeyStroke(InputEvent.CTRL_MASK, KeyEvent.VK_DELETE);
     "alt shift X" => new KeyStroke(InputEvent.ALT_MASK | InputEvent.SHIFT_MASK, KeyEvent.VK_X);
     "alt shift released X" => new KeyStroke(InputEvent.ALT_MASK | InputEvent.SHIFT_MASK, KeyEvent.VK_X, true);
     "typed a" => new KeyStroke('a');
 </pre>
 For backward compatability, this will return null if <code>s</code> is
 not in the above format.<DD><DL>
