ACCESS

From RelicWiki

ACCESS is a key combination in Homeworld that will result in the scuttling of one's fleet.

Newbies were often told that ACCESS was a cheat code that would do various things when typed at the start of the game - create a free heavy cruiser, win the battle, etc. - in hopes of getting them to humiliate themselves by falling for the trick.

In the same vein, SUCCESS was also on WON rotation, albeit not as known or popular as ACCESS.
