Translation to foreign languages

The "Save online" window, opened from the "File" tab in the Brazilian Portuguese version has two buttons: "Meio", on the left and "Cancelar", on the right. Now, "Cancelar" is quite OK, but I'll be damned if I know what "Meio" means!! I'm Brazilian, BTW.

Please, anyone tell me what the original English version has for the label on this button, so I can suggest how to fix this bad translation.

BTW, "meio" in Portuguese, means "half", "middle", or "right in the center", none of which seems to make sense as a label for that button.
