JJ,

What's more annoying is that, the kernel ignores injected power
management scancodes when sent using SendInput(). This makes
it impossible to have a custom key or shortcut to act as power
management key,

Yup, I could imagine a use for that. And some very nasty "jokes" on
someone elses 'puter too.

unless we manually call a power action function ourselves.

but as those are available ... :-)

I was thinking of translating those two (three when including the "wake from
sleep" key) to some multimedia keystrokes - which result in calling
predefined programs (browser, email, etc). But nope. :-\
