Setting time to autosave

I’m fairly new to Pressbooks, and I believe awhile back I was able to increase the amount of time before an autosave kicked in on a page; I need to do that within another book, and I can’t recall where I did that. Can someone remind me where that setting can be changed? Thank you!

I think that WordPress has a default 60 second to autosave feature, which you can adjust in wp-config.php. See for details. I’m not aware of Pressbooks adjusting the default anywhere in our codebase.
