How can Smalltalk codes in Squeak be automatically indented?

I was wondering if Squeak has some automatic indentation function to make codes in disorder become clean and well-indented in a flash, just like what we can do in VIM and MS VISUAL STUDIO.

Any good methods to make that happen ?

Solution

There is an auto indent on new line preference:

And you can pretty-print a method from the shift-click popup menu:

Moreover, you can automatically have each method pretty-printed upon viewing it by clicking on the rounded "source" button on the far right of the button ribbon in the System Browser. But beware that the pretty-printing does not always make the code actually prettier than the way as it was saved.
