Actually, the command line I'm talking about is inside the editor itself. The keypress you use to bring it up varies between the different editor emulations, it's Escape in CUA; but if you click down on the left side of the grey status bar at the bottom of your editor window, the command prompt textbox will appear, and you can type the commands in there.
Sorry about that, I'm so used to using that myself, I forget that it might not be obvious for new users, or certain types of workflows.
