One of the most carpal tunnel / repetitive stress inducing clickers in this game is clearing all the acknowledge messages.  On the good side each of them have an icon so you can look at which you want to pay attention to.  On the bad side, there is no way to control this messages with more finesse - like in Paradox games where you can turn on / off a class of messages.  Even worse is that these tiles that pop up are devoid of some of the critical info about the event "The Olmecs have changed their opinion of you" for gods sake man show me the FROM > TO right in the message don't make me go to their screen!

So what I'm wondering is if there is a hotkey for clearing the tile - that would in effect hit the Acknoledge button for me?
