screenshot of no list of spellers
We should be able to change the spelling language by right-clicking on the bottom bar or using the language menu, since it always shows "more dictionaries online...".
Thanks to Áron, I was able to change the speller to Portuguese using the "spelling" item in the menu, but it should work out of the box, because there won't be an Áron for each newbie who wants to check spelling in Calc.
