Want to open hidden folder

I want to open a hidden folder via keybiard-shortcut.
I know how to open a vissible folder, but teh hidden folder doen't appear in the dialog, even if hidden files are visible in normal finder-windows.
Any Ideas?

easiest just use the „run terminal command“ action and run „/usr/bin/open ~/path/to/folder“

Thank for your "faster than light" answer.
