does anyone know how to make the one circled in black

How to do what?
I’m guessing the title of your post is in Italian, but very few people here understand it. This is an international forum and we try to standardize on English for that reason.
The screenshot seems to be a copy from the Post V9 thread:
I’m guessing this topic / thread is going to attract a lot of silly responses…
The “hop over” is a new feature just posted in the Post V9 thread. To make use of it you will have to install the current nightly version.
The “feedback” thing is a net directive label. These are already present in KiCad V8.
Firstly, since this is from the Post V9 thread, you have to be using a nightly build (aka 9.99).
Then go to Schematic Setup > General > Formatting and set “Hop-over size” to something other than “None”.
The lower circled item is a Directive Label being used to apply a netname and a netclass. (It’s not terribly useful there; that’s just a test document I was using when I wrote Directive Labels.)
Heh. Cross-posted with paulvdh…
Meh, double up gives OP some confirmation. 
There were a couple of problems with this new function, but our Founder has committed a fix.
I haven’t checked to see if the fix has been released yet.
Duck-unders as well as hop-overs.
I had to chuckle when I saw this announcement, it was the subject of my very first post here almost 10 years ago . . .
You’re not the only one.
This subject has gone off the rails more than once.
