The Preview mode

In Preview Mode your page can be displayed in Internet Explorer. This is an especially helpful tool to see how your page will appear in a web browser. There is no need to save the page before you preview it. When you switch into preview mode, the the toolbar will change to contain one local button and one server button. In addition, there will be one address box where you can type a web address. If you have pressed the server button you can type a address. The web browser will navigate to the page you entered into the address field.

Press the button at the bottom of the edit window, if you want to switch to preview mode.
