Hello,
I've found that the Sysrq Keys on Apple Computers
are 'Keypad+-F13-<command key>', maybe it would
be a good idea to include that in Documentation/sysrq.txt.

Speaking of reversed, there's a slightly "nicer" one in 2.2.18+:
On PowerPC - You press 'ALT-Print Screen-<command key>'.
(And yes, all the apple keyboards I've seen w/ F13 have Print Screen
right below it). Tho I'm also rather sure this didn't get into
Linus' tree until after the 2.3 split..

Which? And it should indeed work with the "alt" key (ie the one for
changing VCs).

Er, 2.2 is mainstream.

But anyways. My objects were it's not just "macs". And not all keyboards
have "F13" written on them as well as Print Screen. Which is why I think
what 2.2 has is what 2.4 should have. Or if yours doesn't say Print Screen:
On PowerPC - You press 'ALT-Print Screen (or F13)-<command key>
As to weather or not it's the key which says "ALT" on it or not, it is the
key which provides the ALT keycode in linux. Or it very well should be, for
consistencys sake.

Err, so? The sysrq code is triggered by "ALT" (which on PPC can be any number
of things, depending on keyboard and other stuff) and the SYSRQ key. It's
either 0x69 or 0x54, which is "F13" in either translated keycodes or ADB
respectivly.

All of the USB keyboards, up until recently.

Well, where does that work? My PReP works fine w/ ALT-printscrn-key
My old pmac is ALT-printscrn-key, and I don't have F13 on my other
keyboard. So yes, I object because I'm not sure where your sugjestion
works.

Yes, as SysRq quite possibly doesn't work on (since none of the keys on it
send the right keycode.)

The old one. :)

Er, I thought you just said you did? What keycodes are you using? Most
"Newworld" only have the F13-less keyboard. Which sort of raises the question
of how 'Keypad +' worked instead of the "ALT" key (either option/alt or the
scroll key, whichever changes VC). Which sounds more like a fluke then
anything else. Which keyboard worked with 'Keypad +' ? The ADB one?
After some quick playing with my oldworld machine, Just F13 - <command key>
is sufficient. I'm not sure about PReP tho (so it's probably not worth
saying you don't need "ALT").

Sounds good.

Nah. I think we should try and fix this sometime tho. Perhaps the round
powerbutton on the keyboard could do 'F13' (and add this to the list..)

FWIW, the F9 key on a G3 PowerBook is labeled "prt screen", and you get that function with the "fn" key, not the "alt" key (which is a secondary label on the "opt" key).
