Command for ctrl+shift+Reset (right click)

Hello,

I'm new to ProStructures but have been a user of Openbuildings Designer for about one year now. I'm trying to customize ProStructures a bit to resemble the methodology, mainly the screen menu that pops up when using the ctrl+shift+reset combination.

I found how to do that but I do have a question.

By default in ProStructures this window/menu comes up when using that combo:

However in the "Button assignment" window I don't see it:

It's not a problem to override the command for ctrl+shift+reset, I can easily do that from the button assignment and it works too! But it means I lose the 'default' menu. I'd like to map that to another button combination.

Can anybody help me out which command I need to enter in the "Action" field to get this menu?

Thank you!
