    - #### DefaultInputHandler

          public DefaultInputHandler(View view,
                                     java.util.Hashtable bindings)

      Creates a new input handler with no key bindings defined.
      Parameters:
        `view` - The view
        `bindings` - An explicitly-specified set of key bindings, must not be null.
      Since:
        jEdit 4.3pre1

    - #### DefaultInputHandler

          public DefaultInputHandler(View view)

      Creates a new input handler with no key bindings defined.
      Parameters:
        `view` - The view

    - #### DefaultInputHandler

          public DefaultInputHandler(View view,
                                     DefaultInputHandler copy)

      Creates a new input handler with the same set of key bindings as the one specified. Note that both input handlers share a pointer to exactly the same key binding table; so adding a key binding in one will also add it to the other.
      Parameters:
        `copy` - The input handler to copy key bindings from
        `view` - The view

  - ### Method Detail

    - #### isPrefixActive

          public boolean isPrefixActive()

      Returns if a prefix key has been pressed.
      Overrides:
        `isPrefixActive` in class `AbstractInputHandler<EditAction>`

    - #### setCurrentBindings

          public void setCurrentBindings(java.util.Hashtable bindings)

      Overrides:
        `setCurrentBindings` in class `AbstractInputHandler<EditAction>`

    - #### handleKey

          public boolean handleKey(KeyEventTranslator.Key keyStroke,
                                   boolean dryRun)

      Handles the given keystroke.
      Specified by:
        `handleKey` in class `AbstractInputHandler<EditAction>`
      Parameters:
        `keyStroke` - The key stroke
        `dryRun` - only calculate the return value, do not have any other effect
      Returns:
        true if the input could be handled.
      Since:
        jEdit 4.2pre5

    - #### getSymbolicModifierName
