Click the Accidental Tool . Handles appear on
any accidentals in the measure. If the handles are obscuring the accidentals you want to move, choose Special Tools > Show Handles to deselect that option.
Drag any handle. If you’ve made the
handles invisible (by deselecting Show Handles), drag the accidental itself.
If you want to undo any accidental repositioning you’ve done, click the
accidental’s handle and press DELETE. To drag the handle vertically, double-click
on the handle and check Allow Vertical Positioning.
