Comment 3 for bug 390552

I am mostly concerned about Win32 support here. The X11 part is definitely feasible. I talked to *** a bit about this and looked at the docs myself: http://msdn.microsoft.com/en-us/library/ms646309%28VS.85%29.aspx

As far as I can tell, Win32 can not support key-release events out of the box. It might be possible if one wants to go closer to the core Win32 API, but I am not sure anyone has time or skills to do that.

Unless we can get a 100% affirmative that this is portable and indeed feasible without jumping through hoops I am going to have to reject it.

Watch this space for updates.
