Emmet is a web-developer’s toolkit that can greatly improve your HTML & CSS workflow: write HTML code with CSS-like abbreviations, use different actions to quickly select and modify HTML and CSS code and more!
Download Emmet.zxp and double-click on it: the Adobe Extension Manager should start automatically and install extension. If you don’t have Extension Manager, you can download it from here.
When installed, check out Commands > Emmet menu for available actions.
You can use default Keyboard Shortcuts… dialog to change action’s keyboard shortcuts.
Emmet for Dreamweaver supports extensions: you should open Commands > Emmet > Emmet Preferences dialog and enter absolute path to extentions folder. Unfortunately, Dreamweaver doesn’t support folder picking dialog so you have to type it manually.
