Select Edit > Keyboard Shortcuts (Windows) or Dreamweaver > Keyboard Shortcuts (Macintosh). From the Commands pop‑up menu, select a command category. In the Commands list, select a command and then select a shortcut to change. Click in the Press Key and enter a new key combination. Click the Change button to change the shortcut. Note: If there is a problem with the key combination (for example, if the key combination is already assigned to another command), an explanatory message appears just below the Shortcuts field and you may be unable to add or edit the shortcut.
