I did find it. Not so intuitively, it is a Nautilus preference. Sorry for being pushy. Probably had set it the way I wanted in Ubuntu and then forgot about it.
Maybe someone else could help with question #2. I run Mac and Windows as well, but I do use shortcuts -- long habit from the days when I ran Mac only. Now that I run multiple OSes, I try to use uniform shortcuts, like Alt-Tab (Com-Tab on Mac) and a few others. I can adjust most shortcuts in gnome using metacity or compiz, but this Menu command is resistant.
This is resolved as well. Set the shortcut by right-clicking and selecting prefs. The trick is that for this shortcut, one must reboot for it to take effect.
