Magical Macintosh Key Sequences

It's pretty sad that there are so many "hidden" things in an OS that's supposed to be so easy to use. I hadn't thought about it before, but the sheer volume of them has surprised me. I knew of the existence of a lot of these shortcuts myself, but I'd never tried to think of them all at once until I started compiling this page. Now that I have many of them in one place (there's more to be added - I think there always will be), I find myself wondering about ease of use. Anyway, enjoy.

On Boot

Key CombinationEffect
mouse down Eject removable media ( I think Boot ROMs prior to 2.4f1 excluded the CD drive )
opt Bring up OF system picker on New World machines - boot to 9 on pre-New World machines
F8Bring up Mac OS X boot partition selector (DTKs only?)
cmd-periodWhen OF system picker is active, open the CD tray
cmd-opt Hold down until 2nd chime, will boot into Mac OS 9 ?
cmd-x (or just x?) Will boot into Mac OS X if 9 and X are on the same partition and that's the partition you're booting from.
cmd-opt-n-d prevent native drivers from loading (System 7 until 9.x?)
cmd-opt-shift-delete Bypass startup drive and boot from external (or CD). This actually forces the system to NOT load the driver for the default volume, which has the side effect mentioned above. For SCSI devices it searches from highest ID to lowest for a partition with a bootable system. Not sure about IDE drives.
cmd-opt-shift-delete-# Boot from a specific SCSI ID # (# = SCSI ID number)

cmd-opt-c-i(Mac IIci only) Set date to 20 Sep 1989 to get a graphical easter egg
cmd-opt-f-x(Mac IIfx only) Set date to 19 Mar 1990 to get a graphical easter egg
