Basically the title. If it feels like the new method in iOS 17 of hitting the plus symbol, then scrolling up and then selecting photos in iMessage takes too long you can just long hold the plus symbol and it’ll short cut to pics.
Edit: Also you can drag and rearrange apps in the + menu as well.
You’re right, looking for them in Books works really bad. As another commenter said, it looks like for iOS 17 is still not available.
On a side note: I just saw that you can look up an interactive version of the manuals through the “Tips” app. Much more user friendly and it contains everything that is in the eBook - albeit still iOS 16 even though my iPhone is up to date.
I had seen some of the stuff in tip (did not realize that was an actual app that I could look at again, thank you) but see nothing in it about the long press stuff sadly.
Yeah I think it is a new feature of iOS 17, the manual of which seems to be still missing
