We are currently piloting Design Studio, our new email design system, and making some information available to customers. If you don’t have access to Design Studio, please continue to use our other email editors.
There are a number of keyboard shortcuts you can use to access Design Studio functionality. You can see a full list of shortcuts at any time by clicking the Shortcuts button in the bottom right corner of the Code Editor. Any shortcut that uses CMD on Mac will use CTRL on Windows (and vice versa).
