Hi Vinicius,
You currently can't "run" scripts from the Code extension (I know - boo!).
For now the simplest is to keep a portal window up on the debug screen - and just switch and run the script from there upon save. Note that you don't need to load fresh script contents or anything - the servers automatically run the latest version - even if it's not currently what's showing in the Portal editor screen...
[Note - there are improvements to the Portal script editor coming in 5.9 - so that it's windows update more quickly and more reliably if the script has been edited elsewhere <-- exactly for this use case].
Paul.
