The window resizes itself to accommodate the new size. The Window Size option simply calculates the total size (in kilobytes) of text and images on the page, divides it by a specific bandwidth target, and presents the estimated download time. In Chapter 5, "Defining Preferences," we'll review options for defining the bandwidth target as well as defining your own custom window sizes.           Context Menus One of the most under-used features in Dreamweaver is that of the context menus. To enable a context menu, simply right-click an object within the Document window.

As we progress through features, we'll certainly cover options available within context menus. For now, let's do a simple cut and paste example using the Document window's context menu. You can follow along by performing these steps: 1. Type some text in the Document window. I'll type Hello World. 2. Highlight the text by selecting one end of it and dragging over to the other end. 3. Right-click the selected text and choose Cut from the context menu. The text disappears. 4.
