[Avodah] insert the slichos

[SBA]

From: "Michael Kopinsky" < >
Lately, I have been davening maariv out of a small German siddur, published
in Basel in 1974.  

1) In the middle of the bracha of S'lach Lanu (right before "ki mochel..."),
it has a note saying "An Fasttagen schaltet man hier im Morgengebet die
Slichos ein," which according to my best approximation (and Google
Translate), means, "On fast days, insert the slichos here in the morning
prayers."
What minhag is this referring to?  Slichos in the middle of shemoneh esrei?!
==========

Correct. During hoych shemona esra.
That is the way our main Nusach Ashkenaz minyan does it.
It must be a Oberland and yekkish nusach.
