History and up/down is apart of #2704. It has patches that include the up/down change, but I don't expect to use any of them as they are. I tried Shift/Control/Alt - Up/Down and none worked. Rebinding just Up/Down did (in Shell only, leaving up/down unchanged in Editor). But not having up/down work to move between lines in the Shell multiline statement entry area is not acceptable to me. I don't know if modifiers can never work with up/down or if there is something that would make it work.
