so you are looking for the .pdf for the 2.5+ versions

i the older (2.49 and before) versions you could open  the cheat sheet in the bottom of the screen and even keep a log of what the last ???? actions were

the 2.5 will keep a history as well   im just trying to remember how to set it up and view it

ill have to do some more research into that and id say also ask this on the daz forums in the old   blender anyone thread that you started
