Such a list doesn't exist for the Echo any more than it does for your cell phone. The Echo is integrated into IFTTT, so any of the actions here [1] are available, and there are also an ever expanding list of actions called 'Skills' [2] that you can add to your particular Echo's list of available integrations (like installing a phone app). That's all in addition to the basic things it can do out of the box, like set timers and reminders, manage a todo list, play music and books (from an admittedly limited set of sources), tell (mostly bad) jokes, sync with your google calendar and respond to questions about upcoming events, tell you the weather forecast, read off headlines, and a bunch more. To a greater or lesser extent, it's like a living room installation of Siri.
