[Kde-i18n-pt_br] Question About Header Capitalization (2nd try)

[Mauricio Piacentini]

(First one was posted from wrong address to the doc list, sorry)

Hi, people. I have a question from the pt_BR team, which is currently 
undergoing a new surge of activity, with lots of new people and energy 
resulting from our first Brazilian meeting.
The question regards capitalization of menu items. According to the 
usability wiki, these should use header capitalizatio:

http://wiki.openusability.org/guidelines/index.php/Guidelines:Menu_Items

So in this case:

Save As -> Salvar Como
Open File -> Abrir Arquivo

Some people consider that this is not "proper" Brazilian Portuguese, and 
that we should do regular capitalization, like:

Save As -> Salvar como
Open File - > Abrir arquivo

Others reasoned that in titles it is OK to use header capitalization, 
even in Portuguese, and this includes for example names of songs and 
other situations.

MacOSX and KDE3.5 in Portuguese use header capitalization, but Vista is 
not consistent, with most programs (including Office, Firefox) going for 
the sentence form, even in menus.

I would also like to request comment from people involved in KDE 3.5 
translation, and also our Gnome pt_Br friends, if possible. They seem to 
use header capitalization for menus as well (consistent with KDE 3.5).

So, is this an usability guideline that should be followed in localized 
versions as well? What do other Latin languages do, and what do our 
friends in the Portuguese team do in this case?

Regards,
Mauricio Piacentini
