We now use a 32-bit structure to describe each key, and an `uhk_key_t` type that wraps all the supported things into a union. But this is not the only change: to be able to move the Fn/Mod keys anywhere, instead of hardcoding their location, they are now proper layer keys. To make it easier to handle turning a layer off, key releases can be handled explicitly, too. Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>

|
|
* First dimension is the Key ID of a given key. Key IDs are the indices of the
|
|
* of the active keys of the key_matrix_t structure. In case of left half, an
|
|
* offset of 35 is added.
|
|

|
|
* For each Key ID, there are 4 different possible scan codes:
|
|
* - default, when no modifiers are pressed
|
|
* - mod layer
|
|
* - fn layer
