    - #### addTranslation

          public static void addTranslation(KeyEventTranslator.Key key1,
                            KeyEventTranslator.Key key2)

      Adds a keyboard translation.
      Parameters:
        `key1` - Translate this key
        `key2` - Into this key
      Since:
        jEdit 4.2pre3

    - #### translateKeyEvent

          public static KeyEventTranslator.Key translateKeyEvent(java.awt.event.KeyEvent evt)

      Pass this an event from `KeyEventWorkaround.processKeyEvent(java.awt.event.KeyEvent)`.
      Parameters:
        `evt` - the KeyEvent to translate
      Since:
        jEdit 4.2pre3

    - #### parseKey

          public static KeyEventTranslator.Key parseKey(java.lang.String keyStroke)

      Converts a string to a keystroke. The string should be of the form modifiers+shortcut where modifiers is any combination of A for Alt, C for Control, S for Shift or M for Meta, and shortcut is either a single character, or a keycode name from the `KeyEvent` class, without the `VK_` prefix.
      Parameters:
        `keyStroke` - A string description of the key stroke
      Since:
        jEdit 4.2pre3

    - #### parseKeyStroke

          public static javax.swing.KeyStroke parseKeyStroke(java.lang.String shortcut)

      Converts a string to a Swing KeyStroke. The string should be of the form modifiers+shortcut where modifiers is any combination of A for Alt, C for Control, S for Shift or M for Meta, and shortcut is either a single character, or a keycode name from the `KeyEvent` class, without the `VK_` prefix. Returns null if the string corresponds to multiple KeyStrokes (e.g., "C+e C+COMMA").
      Parameters:
        `shortcut` - A string description of the key stroke
      Since:
        jEdit 5.0

    - #### setModifierMapping

          public static void setModifierMapping(int c,
                                int a,
                                int m,
                                int s)

      Changes the mapping between symbolic modifier key names (`C`, `A`, `M`, `S`) and Java modifier flags. You can map more than one Java modifier to a symobolic modifier, for example :

      ``

                  setModifierMapping(
                          InputEvent.CTRL_MASK,
                          InputEvent.ALT_MASK | InputEvent.META_MASK,
                          0,
                          InputEvent.SHIFT_MASK);

           You cannot map a Java modifer to more than one symbolic modifier.

      Parameters:
        `c` - The modifier(s) to map the `C` modifier to
        `a` - The modifier(s) to map the `A` modifier to
        `m` - The modifier(s) to map the `M` modifier to
        `s` - The modifier(s) to map the `S` modifier to
      Since:
        jEdit 4.2pre3

    - #### getSymbolicModifierName

          public static char getSymbolicModifierName(int mod)

      Returns a the symbolic modifier name for the specified Java modifier flag.
      Parameters:
        `mod` - A modifier constant from `InputEvent`
      Since:
        jEdit 4.2pre3

    - #### modifiersToString

          public static java.lang.String modifiersToString(int mods)

    - #### getModifierString

          public static java.lang.String getModifierString(java.awt.event.InputEvent evt)

      Returns a string containing symbolic modifier names set in the specified event.
      Parameters:
        `evt` - The event
      Since:
        jEdit 4.2pre3
