Diacritical Marks in Microsoft Word

A diacritic is a glyph (an element of writing) that is added to a letter for clarity in meaning.
 Diacritical marks may appear above or below a letter, or in some other position such as within the letter or between two letters.
The main use of diacritical marks in the Latin-derived alphabet is to change the sound value of the letter to which they are added.  English is one of the few European languages that does not have many words that contain diacritical marks.
For keyboard shortcuts in which two or more keys are pressed simultaneously, the keys to press are separated by a plus sign in Microsoft Word.  For keyboard shortcuts in which you press one key immediately followed by another key, the keys to press are separated by a comma.
To type a lowercase character using a key combination that includes the SHIFT key, hold down the CTRL+SHIFT+symbol keys simultaneously, and then release them before typing the letter.
