I can't change the text format as I'd like.

@Andreas_Hegenberg I want to use the predefined action to change the text format. I just want the text to be strikethrough. Everything else should stay the same (bold, italics, etc.).

So this isn't the result I'm looking for. Can you please help? Thanks.

Unfortunately parts of this depend on the app you are trying to use it on. Is there a specific app you try this in?

Yes, if possible, I'd like that for Devonthink and Scrivener.
