/** Modifiers (other than SHIFT) not delivered with KEY_TYPED.
  *
  * 1.2beta3 & 1.2beta4
  * Solaris 2.6, BUT NOT WinNT
  *
  * In the Solaris environment, the ALT, CTRL, & META modifiers are
  * never set in a KEY_TYPED KeyEvent for a Lightweight component.
  * They are set in a WinNT environment.
  *
  * Consequently, ALT-a causes an "a" to be entered in the JTextField
  * (& similar components) in the Solaris environment, but not with WinNT.
  * Also, mnemonic and accelerator keystrokes are sometimes entered in these
  * Components because of this.  Also, there are other platform
  * inconsistencies with KEY_TYPED when you combine modifiers.
  *
  * Note that the KeyEvent API doc,
  * http://java.sun.com/products/jdk/1.2/docs/api/java/awt/event/KeyEvent.html
  * and the "Writing a KeyListener" tutorial,
  * http://java.sun.com/docs/books/tutorial/ui/components/keylistener.html,
  * state that KEY_TYPED is used when a combination of characters maps to
  * a Unicode character.  So it is unclear whether a KEY_TYPED should be
  * sent at all.  (Since when does ALT-a map to Unicode "a"?)
  *
  * But at the very least, the Solaris behavior should change
  * to match WinNT so that Components and Listeners can easily
  * recognize normal character input.
