Undo and Redoe93 remembers undo/redo information only for operations that change the text of a buffer. It does not remember cursor movements, or selections. Unlimited amounts of undo information are recorded separately for each buffer. e93 groups character insertions and deletions so that they become single undo items. Each time you undo in a buffer, e93 remembers what was undone as redo information. However, once you make a change in a buffer, all redo information is lost.
