You just type it in at a normal speed, slow or fast at your discretion.
Like this: You've just started up the game for, uh, Dover in Britannia. You see your little outpost and everything. You simply type in -giveall with the dash and everything, bam you see you gained a ton of every resource at the top-right. There's no input box, no console, no chat or anything like that. Just type it in.
I don't see why this is such a hard concept for everyone to grasp.
Maybe because they can't be assed to figure it out. - Thats my tipical atitude XD
