There are some cheats posted here. Ive used them in the arena to test out stuff and they seem to work.
http://dwarffortresswiki.org/User:VjekThink there is a description in there somewhere how to use it.
If you still dont understand just copy paste the lua codes under the version you are playing and put each one in a separate notepad file in the lua folder in the hacks folder. Then just rename the file extensions to .lua instead. To use the codes in adventure mode you need to open your character screen and then type them in the dfhack console. There is a list of skill tokens in the dwarf fortress wiki for specific skills.
Cheating makes the game really boring though... the only one I sometimes use is butchering because getting food is boring.
