configuring keyboard shortcuts

Dear list,

I just discovered the Tools > Customize > Keyboard feature of
OpenOffice.  I would like to get some emacs keybinding configurations
up.  I am using openoffice v 3.2.0 on Ubuntu 10.04 64bit.  I ran into
the following issues while defining shortcuts in Calc.

1.  When I try to save, I get an EMPTY (0 byte) file.
2.  Reset does not work (both buttons).
3.  Can I define additional shortcut keys (like Control [ and Control
])?  I have a feeling this is in some config file for openoffice.
4.  Can I use the Win Key as an additional modifier for additional shortcuts?
5.  What is the difference between "OpenOffice.org" and "Calc" when
defining shortcut keys?  Clicking on either appears to be the same
when in Spreadsheets.

Thank you for your help.
