The English International keyboard (available on both Win/MacOs) has support for diacritics without any Compose key (~n => ñ, 'e => é, `a => à). The drawback is that certain characters have to be confirmed by the space bar to be used as stand-alone character. A life saver for a French immigrant in the US like me.
