# Generic key layout file for full alphabetic US English PC style external keyboards.

# This file is intentionally very generic and is intended to support a broad rang of keyboards.
# Do not edit the generic key layout to support a specific keyboard; instead, create
# a new key layout file with the required keyboard configuration.
