How to use pycharm to auto indent the select area by the template of the coding style

Well, In eclipse, I can set the code-style template , when the code finish, I could indent it by the template. For example,

In the coding style template, I set the style is as following:

aDict = {1: 'a', 2: 'b'} ## that is each variable got a whitespace in front of it

If I write the code like this

aDict = {1:'a',2:      'b'}

How can I indent the code after I wrote it?

I tried the "code-Auto Indent Lines", which is binding to Hot-Key "Ctrl + Alt + I",but It seems doesn't work
