Undo tree is a mode to navigate in the history of recent changes. I think it's better to use this mode for deep undos

Answer 2

Hold down Alt, type 2 0 0, then press CTRL+x u.

This gives an argument of 200 to the operation you are going to perform next (e.g. undo), so it applies that operation 200 times.

By the way, CTRL+/ is also mapped to "undo", if you would like to use fewer keystrokes.

Finally I found additional way of doing so: C-x u C-x z z z z z

But ctrl / is easier.
