The Assets panel allows you to select multiple assets at once. It also provides a quick way to begin editing assets.
Shift-click to select a consecutive series of assets.
Control-click (Windows) or Command-click (Macintosh) to add an individual asset to the selection (whether or not it’s adjacent to the existing selection). Control-click or Command-click a selected asset to deselect it.
When you edit an asset in the Assets panel, the behavior varies according to the asset type. For some assets, such as images, you use an external editor, which opens automatically if you have defined an editor for that asset type. You can edit colors and URLs in the Favorites list only. When you edit templates and library items, you make the changes within Dreamweaver.
Double-click the asset.
Select the asset, then click the Edit button .
If the asset is file-based (anything other than a color or URL), save it (in the editor you used), and close it.
If the asset is a URL, click OK in the Edit URL dialog box.
