There are three ways to add accents to letters in Microsoft Word 2013: keyboard shortcuts, the Windows Character Map and a change in Language Preferences.
Using Keyboard Shortcuts
Keyboard shortcuts are often the fastest way to type accented characters in a Word document. For accented letters, these shortcuts all use Ctrl or Ctrl-Shift with a symbol, followed by the letter you want accented.
For example, to use an accent grave, press Accent Grave -- located beside the 1 on most keyboards -- and the Ctrl key at the same time, followed by a letter. To type a capital letter, hold the Shift key just as you would when typing without an accent.
Microsoft has a comprehensive list of keyboard shortcuts for international characters, which you can bookmark for future reference.
Using the Character Map
If you can't remember the keyboard shortcut for an accent, use the Windows Character Map. This tool presents a small window you can keep in the corner of the screen while you work on a document. To launch Character Map, type "character map" in Windows Search.
To make formatting easier, click the Font menu in the Character Map window and select the font you're using. The default font for Word 2013 is Calibri. Of course, you can use any font in Character Map you wish, like Arial or Times New Roman, and then simply change the font in Word after the characters are all in place.
Select the accented character you want and then simply drag it onto the Word document where you want it to appear.
Another method is to click the Select button after you've clicked the character you want, then click the Copy button. Place the cursor in the Word document where you want the character to appear and press Ctrl-V to paste it, or right-click and select Paste.
Changing the Keyboard Layout
If you're proficient in a language, consider adding it to your Windows language preferences. New system languages change the keys on your keyboard to any international keyboard you need. The key labels won't always correspond with the letters you get after changing to another language, however.
To add a new language, hover the cursor at the bottom of the Windows desktop to reveal the Taskbar and then click your current language, which is ENG for English keyboards. Click Language Preferences.
Select the language you want in the Add Languages window. After the language is installed, you can switch to it at any time from the Taskbar. To toggle through each of your languages, press the Windows key and Space Bar simultaneously. Unless you actually have an international keyboard, you'll have to memorize the placement of the new key locations.
If you have a touchscreen monitor, the virtual keyboard will change to the new language too. To launch the virtual keyboard, just click the Keyboard icon in the Taskbar.
