Using the Mirror tool, you can create a 
 measure that contains intelligent copies of individual notes from several 
 normal measures. The resulting patchwork measure is called a composite 
 mirror. 
         
        Note. Composite mirroring 
 combines notes from different measures into a single measure. If you want 
 to create a mirror consisting of selected notes from a single measure, 
 copy the entire measure (see To 
 create a mirror, above), and see To rebeam or edit an existing mirror, 
 below, for instructions on choosing selective elements of it. 
        
        
            - Choose Window > 
 Advanced Tools. Click the Mirror 
 Tool  
; then double-click an empty 
 measure (the target measure). The Tilting Mirror dialog box appears, 
 so called because it can be made to “reflect” the contents of any other 
 measure in the score. At the moment, the Tilting Mirror dialog box is 
 blank. 
            - Click the up, down, left, or right arrow buttons 
 to maneuver your “window” on the score to the measure whose notes you 
 want to mirror. Click the UP ARROW to move up a staff, the right 
 arrow to move to the next measure, and so on. As you proceed, you’ll see 
 the contents of each measure you view, adjusted for the target measure’s 
 clef. (If you move your “view” to another mirrored measure, it appears 
 blank in this window.)
 
            - When you’re viewing a measure whose notes you 
 want to mirror, drag the cut bar handles inward to enclose the desired 
 notes. The “cut bars” are the dotted lines at each end of the window, 
 whose handles you drag to move them.
 
            - Click Next. Finale keeps track of the 
 notes you just selected and restores the cut bars to the ends of the window, 
 ready for another set of notes.
 
            - Repeat the last three steps, as necessary. 
 Use the arrows to locate the measure, the cut bars to identify the notes, 
 and click Next to add the selected notes to the target measure. To remove 
 one of the elements of your composite mirror, click the Prev (or Next) 
 button until the notes appear in the window; then click Delete. If you 
 want to insert a new selection between two existing ones, click the Prev 
 or Next buttons until you’re viewing the selection after the insertion 
 point; then click Insert. Use the directional arrows and cut bars as usual. 
 
 
            - Click OK. The Mirror Attributes dialog 
 box appears. Specify a transposition, and specify musical items to ignore 
 (Don’t Draw), as needed.
 
            - Click OK (or press ENTER). 
 The composite measure appears in the score with a mirror icon. If any 
 of your measure-fragment selections were blank, any selections after the 
 blank selection are ignored.
