I have converted "; " into null tag multiple value separators using 'split field by separator "field": "; "
I now have all my multiple fields separated by nulls, shown as \\ in the field values. Some of my devices and apps don't behave well with the use of multiple fields and nulls. I cannot find a way to replace \\ back to anything else!!!
I swear I managed to with a previous version using something like \\\\ to find the \\ in the displayed field value.
I can manually replace them on an individual basic but can not create an Action to do it for me...
To add insult to injury I had to edit this post 4 times to get \\ to display (two \s need to be entered as 4 \s)
\ 1\
\ 2\
\\ 3\
\\ 4\
\\\ 5\
\\\ 6\
And the final \ at the end displayed without being entered as a double provided that was the end of the post. Adding another line required it to be entered as 2... I need a beer now.

You can enclose special characters in `

The double backslash are not real characters in the tags. They just indicate that there is a multi-value field, which you can see, if you press ALT-t in Mp3tag.
If you don't want multi-value fields but just multiples values in one field, you can do that with an action of the type "Merge duplicate fields". There you can also define your personal separator between the values

Example for multiple existing fields ARTIST and a semicolon space `; ` as separator for the new single merged ARTIST field:

Thanks for the swift replies, guys. There is no mention of \ as a special character in the documentation (that I can find). I'm not a programmer, but I guess it has some general (HTML?) meaning. The fact that the break is displayed as \\ is the key.
Manually editing \\ back to "; " and saving the tag removes (merges) the double field. Alt T is a Godsend - again not intuitive.
Merge duplicate fields is exactly what I was looking for!

This is the syntax that the forum software (Discourse) and its comment parser is using.
This has nothing to do with the Mp3tag software itself. Therefore, no information can be found in the Mp3tag documentation.
BTW: If you use the search function in the upper right corner in this forum and use search words like "replace double backslash" you would find some existing entries like [Find & Replace double backslash?](https://community.mp3tag.de/t/find-replace-double-backslash/66916)

Ah - my failure to find that was because I used `\\` instead of saying double backslash!
