43 * @keycode: the hardware keycode. This is an identifying number for a
45 * @group: indicates movement in a horizontal direction. Usually groups are used
46 * for two different languages. In group 0, a key might have two English
47 * characters, and in group 1 it might have two Hebrew characters. The Hebrew
48 * characters will be printed on the key next to the English characters.
49 * @level: indicates which symbol on the key will be used, in a vertical direction.
50 * So on a standard US keyboard, the key with the number "1" on it also has the
51 * exclamation point ("!") character on it. The level indicates whether to use
52 * the "1" or the "!" symbol. The letter keys are considered to have a lowercase
53 * letter at level 0, and an uppercase letter at level 1, though only the
54 * uppercase letter is printed.
56 * A #GdkKeymapKey is a hardware key that can be mapped to a keyval.

78 * A #GdkKeymap defines the translation from keyboard state
79 * (including a hardware key, a modifier mask, and active keyboard group)
80 * to a keyval. This translation has two phases. The first phase is
81 * to determine the effective keyboard group and level for the keyboard
82 * state; the second phase is to look up the keycode/group/level triplet
83 * in the keymap and see what keyval it corresponds to.
