Something odd has started happening with Layout.
I have a drawing with a number of pages, one of which is entitled Roof. If I am on a different page and start typing anything starting with letter R anywhere, I am immediately transported to the Roof page. I first noticed it when trying to rename another page Rafter Layout. I can type “after Layout” but if I try to add the R, it won’t accept it and I am again taken to the Roof page. It is almost as I have inadvertently invoked a shortcut I didn’t know I had.
