I am working on a slideshow in Spanish. Pages has the "More" tab on the inspector which allows you to change the language of the selected text / document, but Keynote lacks it.
I know you can spellcheck using Edit > Spelling > Spelling... but apparently this system spellchecker is independent from the document language. The checker will check in spanish, but spanish words in the document are still be underlined in red.
Is there any way to change this? Not only check for spelling in another language, but actually change the document's language and make the red lines disappear?
