Like in many of the Adobe programs Dreamweaver will allow you to set custom keyboard shortcuts. I use Dreamweaver almost solely in Code View and have added 2 custom shortcuts that I use all the time that I thought I would share.
Ctrl + Shift + H = Apply html comment to selected code
Ctrl + Shift+ C = Apply /* */ (CSS) Comment
Here is how to set your Dreamwaver up the same way:
First to set up a custom keyboard shortcut go to Edit > Keyboard Shortcuts.Under the Commands drop down choose Code Editing.
Scroll all the way to the bottom of the window and about in the middle you will see Apply html comment and Apply /* */ Comment.
Highlight Apply html Comment and in the box that says Press Key hit the shortcut Ctrl + Shift + H. Hit Change.
Repeat for the CSS comments.

Hope you get as much out of the shortcuts as I do!
