This whole time I was convinced that Apple just re-bound my favorite keyboard shortcut to something else in Xcode 26 and I just needed to find it and re-bind it, but it looks like they've gotten rid of it altogether and I'm losing my mind.
For many years, selecting a type in the Open Quickly menu (Shift-Command-O) and hitting Shift-Option-Enter would bring up a chooser that would let you move a cursor around and select which open pane to open the file in (or create a new pane.) It was so useful and made working in Xcode so fast and it really seems like it's gone for good.
Has this behaviour been changed? I don't see it mentioned in "What's New in Xcode 26?"
