How do I change case in Scrivener from upper to lower case and vice versa on an iPad?
Any ideas about this?
As far as I know, retyping works, but there is no other method within iOS Scrivener to address this.
Glad to see you have a sense of humour! 
I end up copying what I need to change into the DRAFTS app, changing it and copying it back. Quicker than retyping.
I would have suggested an external app, but don’t use one so I had no idea which to suggest. Drafts is certainly popular enough, but I don’t have it installed.
MIght this app, in conjunction with a Shortcut, help?
