Usually the internal level of a heading element is well defined. Part is -1, Chapter is 0, Section is 1 and so on. Currently I'm trying to separate certain parts in the appendix of my document. For this I use the
\part command. Since the document itself is
scrartcl the highest level I use is
section. Within the document the usage of part looks as it should, however, in the table of content it is differently indented and in a larger font size.
An alternative is to define a custom command that creates a part-look-a-like page and manually adds the title parameter to the TOC. However, I'm curious, is there a way to manipulate the internal TOC level of a heading element? For example, change the level of part from -1 to 1. This should result in the behavior that a part is within the table of contents is displayed like a section.
