In addition to accessing tools from the Spatial Analyst toolbar, you can access similar tools, and many more of them, from the ArcToolbox window.

To open the ArcToolbox window, click the Show/Hide ArcToolbox Window button on the Standard toolbar. The window is placed within the application. Its position may vary depending on the windows you have open. From the ArcToolbox window, you can access all the geoprocessing tools available with ArcGIS. There are more than 450 tools, including more than 150 Spatial Analyst tools contained within the Spatial Analyst Tools toolbox. All tools can be run via dialog boxes or a command line.

The ArcToolbox window can be placed anywhere in the application or on the desktop outside the ArcMap window. To dock the ArcToolbox window above the table of contents, click and drag the bar at the top of the ArcToolbox window over the ArcMap table of contents, then release the mouse button to drop the panel. The outline of the ArcToolbox window helps you place it in the desired position.

To make the ArcToolbox window float on top of the ArcMap window without docking, press and hold the Ctrl key while you move the window, releasing it after you release the mouse button.

You can save a map document with a new file name by clicking the File menu and clicking Save As.
