This wizard will insert links to other documents in your site, or on external sites.

The button also allows you to have the link open a new popup window. You can control whether the new window will have a menubar, toolbar etc. as well as the size and position. A new window will still be opened with the link even without Javascript support in the browser, except it will not have the size/position etc. that you defined.
