I should have added an "etc." … the steps I mentioned still wouldn't be the whole acetyl group!

It's not the most friendly builder, but once you play around with it for a while, you can see how the general process works.  Basically to build outward you use the "Modify Structure" tab, with cycles of hydrogen addition and then changing a hydrogen to some other atom type.  You would add hydrogens (could do with AddH the first time around… this tool is also in the Structure Editing section), then change one hydrogen to a carbon of the proper hybridization type, then add hydrogens again, then change one of the hydrogens on the carbon to an oxygen of the proper hybridization type.
