Rated 4 out of 5 stars

Since we use keyboards to type mail, no wonder this add-on saves so much time!

Suggestions for improvement, which I'll also post to a forum once I find one:
• allow mapping to menu commands—some important ones don't have shortcuts, and it'd be nice to be able to type just 'R' to reply
• keyboard shortcuts should be disabled when an HTML text box in a message has focus. Message like that are rare but can be very useful when they exist
• the preferences dialogues could use a bit more explanation; I had to go to the web page to find out what it all meant, and I had to play with it a bit to figure out how to assign keys to the shortcuts I created

Thanks for this!!
