        What it does
        The Smart Shape Menu allows you to flip 
 the direction of slurs.
        
            - Shape Direction: Flip · Automatic · Over · 
 Under. SongWriter makes intelligent decisions about slur direction, 
 based on whether the attached notes are above or below the middle staff 
 line. When you transpose music or change the key, slur directions are 
 automatically changed, without requiring any action on your part. However, 
 there will be times when you’ll probably want to change the direction 
 of individual slurs that are attached to notes. This you can easily do 
 using the Direction submenu.
The Direction submenu offers you four choices: flip the 
 currently selected slur, place a selected slur over the entries; place 
 the slur under the entries; or use automatic placement. Flip and Automatic 
 have keyboard shortcuts of command-F and command-shift-F respectively.
