 Listener Jared wrote in and asked, is there a tool or keystroke I can use to file email messages in Apple Mail? Going into keyboard shortcuts in the keyboard system settings pane would be one way to do that. However, there is an add-on that will do this for you and it is mail act-on. That is the key, no pun intended. It's part of SmallCube's mail suite and includes a couple of other things. Mail act-on is one of them's signature profiles and other, those are the two I use. Mail tags is, I believe, their most popular one. It's just not one that I use, but it's all part of SmallCube's mail suite.
