How can I move an object to preset list of locations, on a path, with control over rotation, translation and speed?

Hi all, I have an object I need to move to a list of preset locations on a path in order using a keystroke, and I need to control the translation and location of the object as well as the time it takes to move. I have found a sample iTween scene that accomplishes nearly what I want, but via an onscreen GUI--I need to use a keystroke. I would like to be able to use the same key each time. I'm not a programmer at all--nearly completely ignorant--so I'll take any info I can find, including pointers to tutorials I may have missed. Thank you.
