How do you add naturals before key change?

[Djard]

Following the convention of classical music notation, I want to add three naturals at the END of a bar, indicating the key of A is ending (key is changing from A to Am). This warning is especially useful to the reader when the bar with the double line, indicating the end of a section, appears at the end of a line on the page. Is there a simple way to place the naturals at the end of a measure?

I would have to see a picture of what you want. The key signature should go after the bar line. If the new key starts in a new system, or on the next page, there should be a courtesy change at the end of the previous line.

Take a look at Document options->key signature->checkboxes :
- cancel outgoing signature
- display courtesy accidentals at end of system

Thanks. The courtesy change worked nicely!
