Layers below are used on top of QWERTY layer defined above.
(Except the PLOVER/STENO layers.)
                                           +-------+
The keys which are shown empty, like this: |       |, represent a transparent key,
                                           +-------+
meaning the key from the underlaying layer (i.e. QWERTY) will be used.
In the keymaps those keys are defined as "_______".

                                           +-------+         +-------+
The keys which are shown solid, like this: | XXXXX | or this |  ...  |, represent an opaque/blocking key?
                                           +-------+         +-------+
Such key is not doing anything in that layer nor allowing the key from the underlaying layer
to be invoked.
In the keymaps those keys are defined as "XXXXXXX".

Most of the modifiers are the same in all layers.
So in most layers they are defined as transparent keys,
letting the keys from QWERTY layer to do the work.

With that idea all the layers below leave the unmodified keys as transparent keys.
In the same time - the layers block the keys that have no sense to be used 
in that given layer. For instance in the cursor control layers 
some of the keys are not used in the layer, but they are blocked to avoid
alpha-keys from QWERTY layer to appear.

For the same reason the keymaps below are shown simplified,
without separate thumbcluster.
