Hi Rosemarie, 

I've been messing around with both open and libre offices writers for about 1 year and a half or so, and found keyboard shortcut lists for both.  I also found the keyboard shortcuts for open office calc.  If you want I can send you those.  I'm not sure if there is an email list, for blind users of these programs though.  I haven't seen anything come across the boards about one. It would be interesting to know if such list are out there.
