Then additional keybindings could be left up to personal customization, so e.g. after activating undo repeating mode with 'C-x u', 'C-z' and 'C-y' could be used to browse the undo history with 'C-x u C-z C-z ... C-y C-y ...' after such customization: (define-key undo-repeat-map (kbd "C-z") 'undo-only) (define-key undo-repeat-map (kbd "C-y") 'undo-redo)
