    <summary>Object for keyboard code manipulation</summary>
    <remarks>
      <para>
    Defines translations from keyboard states to a `keyval`. Two phase translation: determine keyboard group and level 
    for keyboard state, then lookup the keycode/group/level triplet in the keymap and get the corresponding keyval.
    Keycode is the hardware/keyboard code for that key. Keygroup is used for language and horizontal tracking [ "group 1" is english, 
    "group 2" is hebrew]. Keylevel is used to track letter case/alternate representation and vertical movement [ level 0 is "a", 
    level 1 is "A" ; alternately, level 0 is "1" and level 1 is "!" ].

        <summary>
        Gets a list of keycode/group/level combinations that generate a `keyval`. 
        The returned list is stored in the `Gdk.KeymapKey keys` parameter/reference. 
        `uint keyval` is the final value for the combinations being collected.
        `int n_keys` is the total number of combinations found and returned in `Gdk.KeymapKey keys`.
        Level determining the top/bottom symbol and group determining the left/right symbol. 
        On US keyboards, shift changes level and there are no groups. Group can determine language mode, for example, Hebrew/English.
