They appear to have an entire menagerie of keys you can press during
startup to access various modes and controls. Seems very un-Apple like
though to have so many different modes…
The vast majority have been around over 10 years. Seems very Apple like to me.
command-P-R, mouse button, shift, have been around since the original Macs almost three
decades ago, witih the same meanings.
Option and C were added with CD-ROMs.
T was added with Firewire devices.
N and option-N arrived with network boot support, OpenFirmware.
command-v and command-s arrived with OS X 14 years ago.
D added with Intel/EFI.
command-R added most recently with the addition of a Recovery HD volume (used for network
restore of the OS, repair of the primary volume, and booting when the primary volume is
encrypted)
I'm pretty sure the only three in the list that aren't firmware features are
command-v, command-s, and shift which are kernel features (in effect are kernel
parameters).
