How to check multi-language text in PowerPoint 2013?
We often prepare multi-language presentations, usually English-German or English-French. We have the appropriate multi-language packs. How do you check the spelling and grammar of two different languages that are used in the same presentation?
I think you will have to highlight the block of text of the language you want to check, then go to review>language>set proofing language and chose the appropriate language to check the highlighted text.
