Hugely confusing. I've figured out the keys you need to use (press "/" for a handy list), but the whole process is so picky and dull that I can't be bothered to go any further. In short, you have two robotic arms you need to manipulate ("Left" and "Right"). Press "O" to switch between them, press U & D to raise and lower the selected one, and press * and + to move them back and forth. Completely lower the Right object to select a different piece of equipment (type in the name...you can get the names by pressing E). Hit the SPACEBAR to switch between the object's functions, and hit RETURN to do something with the object (like drop the scoop, etc.) I suspect you really need the manual to go any further, though. Figuring out this beast of a program is more of an experiment than any chem lab would be.
