Type in "debugup" during play to get debug mode. You will see coordinates appear in the top right hand corner and Dinos will ignore you unless you shoot them.

Keys to use while in debug mode:

Cheat Code - Granted Wish

CTRL - Run Faster
SHIFT+S - Slow Motion
CTRL+N - Long Jumps
SHIFT+T - Show Frame Rate
TAB - Full Map
SHIFT + L - Unlimited Ammo/Fly mode

For the Fly mode cheat you need to use the mouse and the CTRL-key to fly.
