Hi I would like to view the underline options panel.
Thank you so much for your answers.
go to Character panel > Underline options
This is what I have on my screen:
Is your screenshoot from Illustrator?
This is InDesign forum.
Ignacio is looking at the Properties panel. In it, you can only enable and disable underlining, you can't see or modify its properties (even though the panel is called Properties!).
As Vladan mentioned, Ignacio, you need the Character panel. Apart from Vladan's way of getting there, you can also use the Type menu from the top menu bar, then select Character.
it is indesign Properties panel (not Illustrator properties panel as I asked before)
It´s from indesign
Thank you for your great answers
