— keyboard multiplexer
keyboard driver provides support for basic keyboard
multiplexing. It is built around the idea of a “super keyboard”.
driver acts as a master keyboard consuming input
from all slave keyboards attached to it.
Slave keyboards can be attached to or detached from the kbdmux
keyboard driver with the kbdcontrol(1)
keyboard driver switches all slave keyboards into
mode. Thus all slave keyboards attached to the
keyboard share the same state. The
keyboard is logically equivalent to one keyboard with
lots of duplicated keys.
