I am using (evil-visual-block) and after the block selection pressing capital letter I and then typing what I want and pressing Esc when I am OK.
Now, I see there is a mistake. How to quickly undo everything? Because now when I press the key u for undo it removes only one letter. And when I changed 20 rows it will take forever to change it all.
Now I have to do again a block selection and delete it if I want to go back.
But it would be so much better to be able to undo the whole operation with one undo.
Any idea how to do that?
I am using Spacemacs, so if there is something there like that already it would be even better.
