I always forget which key combinations do what.  Google found this,  
however (I'm going to print a copy and keep it handy):

Command-S Boot into Single User Mode
Command-V Boot using "Verbose" mode (shows all kernel and startup  
console messages)
X Reset startup disk selection and boot into Mac OS X Server
Shift Boot into "Safe Boot" mode, which runs Disk First Aid. A reboot  
will be required afterward.
Option Boot into Open Firmware to select a boot device
Command-Option-Shift-Delete Bypass internal harddrive on boot
T Boot into Firewire target disk mode
C Boot from the internal optical drive
N Start from the Network (NetBoot)
Command-Option-P-R Reset Parameter RAM (PRAM) and non-volatile RAM  
(NVRAM)
(mouse button) Eject (internal) removable media
