NonPrintableKey represents the meaning of a non-symbolic key on a keyboard.
The definition of each key is derived from [W3C named values of a key
attribute][1].
## API version 9 and onwards
Starting from API version 9, the enum value space is subdivided based on the
subsection numbers of the section [Named Key Attribute Values][1], multiplied
by 0x1000.
For example, the keys from section [3.10 Multimedia keys][2] will be located
at `0xa000`-`0xafff`. The values and reservations that were present
in this enum prior to the introduction of the convention have not been moved,
and values that go logically into pre-existing sections have been inserted
into their logical place using the prior convention (see below). This allows
us to extract the section ranges if this is for some reason useful to the
application.
## Prior to API version 9
The space of the nonprintable keys is subdivided roughly to correspond to the
subsections of Section 3 of the document Named Key Attribute Values.
The choice for the section values is arbitrary, so long as blocks of
values are allocated at once, and the keys with similar purpose are kept
together.
## Reserved ranges
The space of possible values for [NonPrintableKey] is subdivided into a
number of ranges, with the intention that the enum values are placed in
the appropriate range when added.
* Special keys: 0x00-0x10
* Modifier keys: 0x11-0x30
* Whitespace keys: 0x31-0x40
* Navigation keys: 0x61-0x80
* General-purpose function keys: 0x9000-0x9FFF
