My personal opinion, which doesn't really matter, is that OOo should have keybindings that make sense on a per platform basis, like what is wanted in this case. There are other issues related to keybindings such as conflicts with gnome unicode direct input, etc. It seems, thought it may not be the case, that they determined which keybindings worked on on Windows (or maybe Solaris) and just forced them on the rest of the platforms.
