PassMark KeyboardTest allows users to quickly check that
all the keys on their computer keyboard are functioning correctly, check
the keyboard LED's, look at the internal scan codes being generated
by the keyboard and measure typing speed.
The down and up stroke of each key is registered and highlighted
on a graphical image of a keyboard. Each time a key is pressed a
variety of state information is updated in the window and on the
keyboard picture.
Possible uses of the software include testing faulty keyboards,
batch mode testing of keyboard in a production line environment, a
typing tutor aid to practice your typing and examining the internal
key codes
