This could be confusing. '?' is for searching backwards, '/' for searching forward. Because we are in a multiline environment, I preferred the Vi keybindings instead of the readline bindings (where '/' goes backwards.)
Also the ControlX-ControlL sequence can complete a line based on the history. (Type "imp"C-X C-L and you get your last import.)
