As mentioned in http://www.jmonkeyengine.com/jmeforum/index.php?topic=10647.new;topicseen (http://www.jmonkeyengine.com/jmeforum/index.php?topic=10647.new;topicseen):
Some key defines are missing from the org.lwjgl.input.Keyboard class, such as the backslash key and apparently the '<' key (on a swissgerman keyboard?). I am using the jMonkey Engine with lwjgl as the backend, and so as a result it gives a warning whenever one of these unmapped keys is undefined.
Please let me know how I can help expedite this issue being fixed. I am not expressly using the backslash key in my game at the moment but it may be necessary in the future. I believe all keys (if possible) should have mappings.
Thanks!
Ricket
