Thanks Leo

Is there any way to download the full document?

A full local copy of the manual is included when you install Opus. Just push F1 to open it.

You can choose whether it opens in a web browser or in the old Windows help viewer via Preferences / Miscellaneous / Advanced [Behavior]: help_interface.

You can also download a PDF version from here, but note that it is not updated as often.

Thanks for the pdf
