PowerMac Keyboard Shortcuts

Hey everyone, I discovered something today working on my MDD.

I found out that if you press Ctrl+F12 (holding down F12) that it will bring up the Restart/Sleep/Shutdown prompt screen. I also found out that pressing Alt and holding down F12 ejects the second Optical Drive of the system.

How did i find this out? I was removing the HDDs on the ATA66 bus to put my main HDDs from the ATA100 bus in that spot. (Just as a temp solution until i get the new MDD Logic Board someone on this forum will send me.
