4. A new entry will appear in your list of folders. At the right end of this entry will appear three dots (when you mouseover the row). Click the three dots and select "Copy Read Only key" or "Copy Read & Write key" depending on whether or not you want the sharer to be able to change what's in the shared folder. They key is now in your clipboard.
