I use MS Word For Mac v. 14.4.7.

Lately, I have been unable to type the letter Capital 'D'. It would automatically jump my cursor to the bottom of the first page of my document, regardless if I were on page 1 or page 4.

Now I am having difficulties with the quotation marks """. It does not jump my cursor, it simply does not type the character/symbol.

I believe my issue is limited to MS Word because I can type D and " easily enough without issue in web forums, emails, etc.

Any suggestions?
