I had been using Synergy for this. But I had stopped using the notification from Synergy as I have been using the Growl notification though Quicksilver. Also, I haven't be using the menu icons from Synergy. So I decided to try Sizzling Keys, since it is a lot simpler.
I have been able to configure the settings the way that I am used to. Also Sizzling Keys is only $5.
