HI Vivien, The OSG already passes back translated keys, or at least that's the current intention. Having some keyboard events pass by translated, and other events pass back untranslated key is a recipe for confusion. It would also complicate user code substantially as event handlers would need to carry state of their own to track the sequence of keydown/repeat/keyup events.
As I said earlier, I believe the right way is to add a field into the GUIEventHandler for translated and untranslated keys, key up, key down, and any key repeat events we might want to generate would set both fields and then users are free to use whichever they prefer. This wouldn't seem to solve the Windows specific problem with bugs in key translation code that you've spoken of though. Perhaps we should just live with them but provide the untranslated key types as well for cases where problems might arise, or just have a bash at writing our own less buggy key translation code.
