How do I redo multiple times in emacs with a shortcut like ctrl+_

Question

I like how I can undo multiple times with ctrl+_, but I can't seem to figure out how to redo that supports multiple times with a similar quick shortcut.

Also, I can't seem to figure out how to skip multiple lines up and down at once.

Sorry if you know this...

You can switch undo to redo by hitting C-g once. So it is not one shortcut key. The behavior is not like as ordinary editor. But I think it is very quick way of redo. See the behavior below.

Emacs undo state changes:

----example1------
time |typed |text
-----+------+-----
1    |      |''
2    |'a'   |'a'
3    |'b'   |'ab'
4    |'c'   |'abc'
5    |'d'   |'abcd'
6    |udno  |'abc'
7    |undo  |'ab'
8    |undo  |'a'
9    |undo  |''
10   |C-g   |''     <---switch
11   |undo  |'a'    <---redo!
12   |undo  |'ab'   <---redo!
13   |undo  |'abc'  <---redo!
14   |undo  |'abcd' <---redo!

----example2------
time |typed |text
-----+------+-----
1    |      |''
2    |'a'   |'a'
3    |'b'   |'ab'
4    |'c'   |'abc'
5    |'d'   |'abcd'
6    |udno  |'abc'
7    |undo  |'ab'
8    |undo  |'a'
9    |undo  |''
10   |C-g   |''    <---switch
11   |undo  |'a'   <---redo!
12   |undo  |'ab'  <---redo!
13   |'x'   |'abx' <---switch
14   |undo  |'ab'
15   |undo  |'a'
16   |C-g   |'a'   <---switch
17   |undo  |'ab'  <---redo!!
18   |undo  |'abx' <---redo!!
