I'm trying to use Inkscape and to support OS projects but sometimes it is a pain

How to change Letter spacing? No chance to use the kayboard way (as described at http://tavmjong.free.fr/INKSCAPE/MANUAL ... g-Keyboard), It doesn't work probably because of keyboard mapping on my notebook.
Is there any other way how to change the Letter spacing in block of text? Why there isn't any way to do it in Text formatting window? So logical to put it there or no?
Thanks for any idea.
