how to highlight multi-line code blocks in geany

In komodo you have code blocks highlighted with a vertical dotted line as shown in the following image here .

Is there anything like that in geany?

Solution

As no one answered me here, I wrote to the geany mailing list and they show me how to obtain this in geany too: it's called "indentation guides", and the setting is in

edit-> preferences-> editor-> display-> show > indentation guides

Thank you to Colomban Wendling of the geany mailing list! I leave this answer here for future reference to help someone else who needs the same.
