"Page Slug" was ist das in deutsch?

Wie heißt das Plugin?

Ich habe mal den Codex befragt:

Title
This is where you enter the title of your post. You can use any words or phrases. Avoid using the same title twice as that will cause problems. You can use commas, apostrophes, quotes, hypens/dashes, and other typical symbols in the post like "My Site - Here's Lookin' at You, Kid". WordPress will clean it up for the link to the post, called the post-slug.

Post Slugs
The Post Slug is the title of your article post in the link, if you are using Pretty Permalinks. The blogging tool software may simplify or truncate your title into a more appropriate form for using as a link. A title such as "I'll Make A Wish" might be truncated to "ill-make-a-wish". In WordPress, you can change the Post Slug to something else, like "make-a-wish", which sounds better than a wish made when sick.

Damit ist wohl also der Titel gemeint, allerdings der "interne" also mit Bindestrichen etc. wie er bei Permalinks vorkommt.
Im Deutschen Adminmenü kann man ihn optional über die Box "Titelform" selber festlegen.
