Quickly change the proofing language for objects on all slides in a presentation.
This feature lets you quickly change the proofing language for all objects on all slides in the presentation — something that is not possible natively in PowerPoint. It also changes the proofing language on Grunt objects.
The top available languages are based on the installed language packs on your computer. To change these, you can go to "Time and language" -> "Language & region" settings on Windows:
In addition, some commonly used languages are available. To set the language, simply choose from the menu in the Grunt ribbon:
Note:
In PowerPoint, it's possible to set language as the proofing language even if the language pack or proofing language is not installed. In this case, no red squiggly lines will appear in your text, since there is no dictionary to do the proofing check towards.
