Word 365, Searching for Errors

I am using Word 365, and trying to do all my own corrections. Does anyone know how to search through a Word Document and find all the blue double underlines, and the dotted blue underline, that indicate grammar suggestions or possible errors? I know how to search and find words, but can you use this search function for these markers?

Thank you in advance!

 

Press F7.

 

Thank you! Can't wait to get done with this in and then I'm gonna switch to Libre

 

The grammar checker in LibreOffice Writer is no better than the one in MS Word. It might even be worse -- although it's open to debate whether or not anything can be worse than Word's grammar checker.
