Writer: Regex search and replace results with hidden text formatting

[Translating-IT]

Hi,

I’m trying to search for strings via regex and have them replaced with the same string but as hidden text. Writer itself does not offer hidden format for search and replace but apparently AltSearch should be able to do so.
The problem is I cannot find out which settings to use in order to get hidden. One thread I found says to use CharStyleName but what name to use for this?

Best regards,
Pascal

Ok, I found out:

Replace: \A{CharHidden=True}
