The keyboard shortcut command - h does not work. But it does from the menu bar drop down under Dreamweaver. On a mac 10.7.4
I can confirm that Cmd+H doesn't work in DW CS6 on a Mac. However, Cmd+Q works every time for me.
When you find what you think is a bug (and Cmd+H is definitely a bug), the best place to report it is through the bug report/feature request form at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform.
