If you define the M4 key as a backlight function on/off key, pressing the M4 key activates or
deactivates the backlight function.
Note that the backlight function on/off key can be assigned only to any one of M1 through M4 keys
and halfway pressed M3 and M4 keys. The key defined more recently will act as a backlight function
on/off key and one defined earlier will be ignored.
That is, if you define the M1 and M2 keys as a backlight function on/off key in this sequence, the M2
key will work as a backlight function on/off key and the M1 key's entry will be ignored.
If a backlight function on/off key is not assigned to any of the M1 through M4 keys and halfway
pressed M3 and M4 keys, the combination of the SF and M4 keys work as a backlight function on/of
f
key by default.

The defined key codes are displayed below “Alternate” in the same
order as entered in the text file.
