JJ,

Power management key codes are "eaten" by the kernel.

It looks like that, yes. I was just assuming (hoping) that the low-level
keyboard hook could at least /see/ those keys (so I knew which ones to try
in the "Scancode map" I spoke of earlier).

Under DOS, user programs can hook the keyboard IRQ handler - thus
can see the power management key scancodes - before they're processed
by BIOS.

Yup, remember that too. Though I normally just hooked the BIOS vector for
them (INT 0x15 IIRC).

Regards
