Not sure if this is addressable or not, but I've always taking the caps lock key and mapped it to Control on my systems. This works in every application I've ever used, except for some games (but oddly, not all games).
SotSE doesn't see the remapping. I have no idea how SotSE gets it's key stroke information, but if there's a way to interpret this it'd be great. I'm constantly hitting caps_lock instead of control to create my groups.
Not a big deal, but if it's a trivial lookupWindowsKeyMap( int rawKeyStroke ) or some such, I'd appreciate it.
