Because of Windows conventions, we've had to switch from the Alt key to the Ctrl key for many of these functions. Clicking Edit from the menu-bar helps in directing you on how to complete these types of tasks and includes notations of the keystrokes that make them go.

Preview provides screen output.
You can access it either through the tool bar or the print dialog box. Use it to check your work on the run, or preview your final product. When you click on the Input icon to return to input from the screen output, you will return to the screen you were on, so you can toggle back and forth between output and input to make quick adjustments. Watch the tool-bar to see how this toggling works. You can also use the tool-bar to zoom in or zoom out for a close or not so close examination of your screen output.
