It works as designed. To navigate between attributes, use the left and right arrow key. You will need to use Enter to lock the cell first.
The tab key will move the cursor to table name field and the customer can use alt+down arrow key to open the list of table and browse through this list. Tab again and the cursor will jump to the Columns tab, then use the arrows key to move to other tabs in the table editor such as Comments, Data.
