I just got my Magic Keyboard for the 2018 iPad Pro 11”. I had seen a Feature Request for scrolling by two-finger gesture on the trackpad on that keyboard.
But more seriously the keyboard shortcuts don’t work at all.
This is not a Feature Request, it is a bug.
The keyboard does work for text entry, like in the text field for the browser filter. But the slash key for bringing up the filter box does not work, nor does ctrl-F for search, ctrl-A for Select All, etc.
