Key Signature Tool

Click this tool, then double-click the measure where you want to change the key signature; the Key Signature dialog box appears, from which you can select the new key. You can also specify whether or not you want any music that's already in the affected measures to be transposed into the new key. You can also use the mouse to drag-enclose a region for a key change.

Contextual menus are reached by right-clicking on the handle of an object or a selected region of measures. A contextual menu will be displayed where you can select a key signature. Right-click a selected region of measures and choose an option from the context menu that appears to change the key signature for that region.
