Format..Choose Document Style missing

OmniGraffle Mac Version 7.8

The doc and several external resources refer to a menu option “Format…Choose Document Style”, but I do not see it. If it’s modal in some way, I can’t guess how.

Thank you for reporting this issue. I have requested an update, so thank you for letting us know.

It is in the canvas inspector now. Tap “Choose…” under Style.
