Firstly, welcome.

You can insert a key change by selecting the required bar where this should occur, and then press Function Key <F5>

In the Bar Settings dialog, you can change the key signature of the song. You can select all choruses, or only specific chorus.

Repeat at a different bar to change the key again if required.
