Mac startup shortcuts

Because I keep forgetting them, here’s a list of buttons you can press during a Mac’s boot to change behaviour:

Key	Action
C	boot from CD or DVD
N	attempt to start up from a network server (NetBoot)
T	start up in FireWire target disk mode
X	force Mac OS X startup
Shift	boot into safe mode
Mouse button	eject CD before booting normally
Command-S	boot into single user mode
Command-V	verbose boot
Option	choose startup disk at boot time
Option-Command-Shift-Delete	Bypass primary startup volume and seek a different startup volume (such as a CD or external disk)
