- JHonaker 4y agoEmacs’s undo system is quite frankly amazing. Not only can you recover any state through an arbitrary number of undo and redo operations, but you can also localize the undo/redo operations to a selected region of the buffer. It’s the number one feature I miss when I’m using another editor.
