* GdkKeymapKey:
|

* @keycode: the hardware keycode. This is an identifying number for a
|
|
* physical key.
|
|
* @group: indicates movement in a horizontal direction. Usually groups are used
|
|
* for two different languages. In group 0, a key might have two English
|
|
* 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
|
|
* letter at level 0, and an uppercase letter at level 1, though only the
|
|
* uppercase letter is printed.

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