You'll probably get scores of replies... Two methods: (1) If on a PC, use Shift-Enter. (On a Mac, there's a separate Enter key on the numeric keypad that does it.) It IS documented, and in a fairly obvious place: From Help Menu, open Documentation Center. Now you noticed that you're dealing with a _notebook_, so it's rather natural to click the "Notebooks and Documents" section there. The first entry in the expanded list is "Notebook Basics"; click that. Right near the top of the page that opens (guide/NotebookBasics" is: Shift+Enter -- do a computation Another way to get there: From Help menu (or from icon at top of Documentation Center home page) open the "Virtual Book". Obviously, look at Introduction. First section there: "Running Mathematica". Obvious next to click entry "Using a Notebook Interface". This opens page tutorial/UsingANotebookInterface", and near the top of that you'll read about Shift + Enter. (2) You used the "computerese" terminology "make the commands in the file execute". Think instead of a more mathematical terminology: "evaluate" something. So from the main Mathematica menu, select Evaluation. You should be able to take it from there.
