Help in Syntax-Editor

[ScrKiddle]

In the Syntax-Editor i press Help in the upper meu.
It opens a website https://www.rj-texted.se/Help/TextEd.ht ... tions.html .
The website tells me:

404
Not Found
The resource requested could not be found on this server!

EDIT:
May the right place is here https://www.rj-texted.se/Help/index.htm?context=49 as the help in general has no sub TOCs with an overview on chapters, this would be the first help page on syntax-editor.
