If you just want to regenerate bonuses, type "map.generatebonuses".
If you are certain that you altered the proper .ini file, then from world builder, you only need to hit "~", and nothing else to get to the proper screen.
Perhaps you don't have the latest patch... not certain if that matters...
Recheck the .ini file. See if the cheat code was properly saved.
I use a PC logitech keyboard... the key is above the "tab" key, to the left of "1". Even though it is upper case on the keyboard, don't press shift+~ or you'll get >> instead of >, and that doesn't work. Of course, your problem is you get neither >> or > or any consule of any kind.
Another idea... the console command line is sort of transparent, and maybe you just dont see it... you should get a semi transparent rectangle, about 1 cm high by 15 cm long, with the command prompt ">" at the far right. Maybe you just missed it. And sometimes it takes a while to come up... maybe if you wait a while... if I recall, world builder is frozen until it comes up... do you get that effect?
Should work, otherwise. If it doesn't, you need more expert help than me.
