How to use the OmniBrowser regex refactor to transform code?

I feel stupid for asking this, but I Googled and found nothing, checked classes
for comments and found nothing, then skimmed Pharo by Example and also found
nothing. Lukas mentioned helpfully in another thread that you can use the regex
refactoring tools in the OmniBrowser to transform code, but I can't seem to
figure out how to do it. I figured out how to "scope" the refactoring to a
class or class hierarchy, which results in a gold window popping up with the
selected class(es) in the left-most panel. When I right-click on the class at
the top and choose "refactor->source regex", I get a template in the code
panel that looks like this:

ORSourceRegexRefactoring new

        "Example 1: Replace symbols with strings"
        replace: '#(\w+)' with: '''$1''' ignoreCase: false;
       
        "Example 2: Replace 4 spaces with tabs"
        replace: '    ' with: ' ' ignoreCase: false;

        yourself

I wanted to rename a method (and all senders of it in the selected scope) from
"nextValue" to "nextItem", so I edit the template to this:


ORSourceRegexRefactoring new
       
        replace: 'nextValue' with: 'nextItem' ignoreCase: false;

        yourself

I highlight it all with Alt-a, then Do It with Alt-d, but nothing seems to
happen.

Hi TJ

The quick answer:
if you want to do a standard refactoring in the scope, like renaming a  
method and update senders, you can use the standard action in the  
menu. It will do exactly what you want.
The rewrite code tool is there for more tricky situations.

The other answer:
I myself often struggle with the syntax for those refex tools. Part of  
the reason I think is that the 'regex' matches on AST nodes and not on  
text, so regex expressions do not match string but nodes.
The links I found useful are the two screencasts of Lukas in the  
following order:

Alt-s... not Alt-d. That was my problem :)

Thanks for pointing me in the direction of those helpful screencasts.

All fine up to here. Just accept the code using Ctrl+S or the item
'accept' in the context menu. Depending on the size of the code to be
searched it might take a while (a hourglass is displayed).
