On my quest to fill in some “gaps” I published the dashkard for Google Reader today. Although you can access a cheat sheet in many Google apps by pressing the ? key in the browser, maybe someone will appreciate having the main Google apps - Gmail, Google Docs and now Google Reader - available through the dashkards widget.
As always, this new dashkard will appear in the dashkard widget’s menu automatically (if you’re connected to the Web).
