[Newbies] How can Smalltalk codes in Squeak be automatically indented ?

[RedTigerFish]

*1 to: 9 do: [ :i |
    1 to: i do: [ :j |
        Transcript
            show: ('{1} * {2} = {3}' format: {j. i. j * i});
            show: ' '
    ].
    Transcript show: ' '; cr.
].*

The above is well-indented codes. Then I intentionally add more spaces, like
this
*1 to: 9 do: [ :i |
             1 to: i do: [ :j |
    Transcript
                 show: ('{1} * {2} = {3}	' format: {j. i. j * i});
                    show: ' '
    ].
            Transcript show: ' '; cr.
].*


Then I use pretty print or pretty print with color, nothing happens.

I recorded a video to illustrate my issue.

I do not understand why "pretty print" does not indent anything.
