Taco HTML Edit Help > Live Preview
With Live Preview, Taco HTML Edit shows you a preview of your document that automatically updates as you edit it. Live Preview can be enabled by selecting "Show Live Preview" from the "View" menu. When Live Preview is enabled, the command changes to "Hide Live Preview". If you need to refresh the preview, then you can select "Refresh Live Preview" from the "View" menu. This command is helpful if you need the preview to be updated to reflect changes in a CSS or an image file that is referenced by the document.

The "Preview" section of the Preferences panel has some options that affect how live preview functions. You can specify whether a horizontal or vertical divider is used to separate the document pane from the Live Preview pane. Also, you can specify if images will appear in the preview, if any Internet files will be downloaded, and if JavaScript alerts should appear.
