The zoom in / zoom out keys have their stated purposes reversed. Unless I'm just looking at it weird. They work fine in the game, just appear to be assigned backwards.
ZOOM_IN,KEY_LEFT_BRACKET
ZOOM_OUT,KEY_RIGHT_BRACKET
TOGGLE_ZOOM,KEY_Z
should be
ZOOM_OUT,KEY_LEFT_BRACKET
ZOOM_IN,KEY_RIGHT_BRACKET
TOGGLE_ZOOM,KEY_Z
