This add-on adds automatic keyboard switching on duolingo based on the user preferences. Multiple keyboards are supported covering most of the courses including Czech, Danish Dutch, English, Esperanto, French, German, Hebrew, Hindi, Italian, Portuguese, Russian and more.
For several languages it is possible to choose different keyboard layouts.
TELEX, VNI and VIQR input is supported for Vietnamese learners.
Additionally a cheat sheet can be shown on screen to assist in learning the keyboard layout.
Developer comments
Linux users who have a system keyboard with deadkeys may experience some unexpected behavior (e.g. unwanted characters appearing). This is due to an upstream bug in firefox ( https://bugzilla.mozilla.org/show_bug.cgi?id=308820 ). The work around is to use a system keyboard without deadkeys.
Since Firefox will only support webextensions from version 57 onwards DuoKeyboard has upgraded to this. In Firefox 52 ESR not all features are enabled by default yet. Please enter "about:config" in the adres bar and set "webextensions.storage.sync.enabled" to true in about:config to be able to use DuoKeyboard.
Duolingo started to roll out a new version of its website around 19-09-2017, it may take some time to get DuoKeyboard compatible with this version.
![On the visual keyboard dead-keys (used to add accents to characters like ["] + [e] gives ë ) are represented in red. Some keyboards come with additional characters which are shown when the "right alt" button is pressed.](https://addons.mozilla.org/user-media/previews/thumbs/218/218553.jpg?modified=1622132578)
