Users of the French Linguistics site may be interested in a text accentuation tool published on our sister Español-Inglés site. The tool, which you can also add to your own web page, blog or social networking profile, allows you to add accents to a short piece of text with simple sequences (e.g. "e/" for an e acute) that can easily be typed from any keyboard. Thus, the tool is useful in cases where your keyboard or configuration does not normally support accented characters easily.
For alternative methods, see the French Linguistics guide on how to type accents.
