Two questions on the Portuguese translation

[Francois Gouget]

Hi,

I noticed two Portuguese translations that look a bit strange to me:

msgid ""
"You don't have a drive C. This is not so great.\n"
"\n"
"Remember to click 'Add' in the Drives tab to create one!\n"
msgstr ""
"se não tem uma unidade C. Isto não é nada bom.\n"
"\n"
"Certifique-se que clica em  ?Adicionar? no separador Unidades para criar "
"uma!\n"

Are the question marks around 'Adicionar' normal? I did not see this 
pattern elsewhere.

msgid "&Search...\tCtrl+F"
msgstr "&Localizar..."

This translation is missing the keyboard shortcut. Is that intentional?
