How can I store a timeline location in Nuendo 13?

Hi!
I have been using the Nuage control surface since 2017 , but now it is broken beyond repair, so I have to use my keyboard form no on. I have scrolled through the entire shortcut list looking for how I can store a timeline location in memory. On the Nuage controller it is a button called memory. store/recall. Does anyone know what it is called in Nuendo?

Regards,

I believe the default key is the insert key. I have a programmed key for a marker region.

Thank you for answering,
But no, it is not the insert key, at least not by default. I have tried it right now. Nothing happens.
I am not thinking about markers. I use markers a lot, but impractical for this use. Now I write the the timecode down on paper and use ten “Enter project cursor position” shortcut to get back.
I am thinking about where to punch in or copy a timecode position and then restore that position when you want to go back to that timeline location, for instance if you are working on a film that has been re-edited and you need to go to the original AAF to find some missing dialogue , you just copy it, restore your position and paste it in. Voila!
