* GdkKeymapKey:

* characters, and in group 1 it might have two Hebrew characters. The Hebrew
* characters will be printed on the key next to the English characters.
* @level: indicates which symbol on the key will be used, in a vertical direction.
* So on a standard US keyboard, the key with the number "1" on it also has the
* exclamation point ("!") character on it. The level indicates whether to use
* the "1" or the "!" symbol. The letter keys are considered to have a lowercase

* A #GdkKeymapKey is a hardware key that can be mapped to a keyval.
