Tell HN: 'd' Shortcut - Full screen compose window in GMail

A common complaint of the "recent" GMail redesign was the small compose window. My muscle memory failed me today and I hit the 'd' key to delete a message. To my surprise a full screen compose window opened in a new tab. This shortcut has probably been available forever but I just found it today and figured others might benefit from this as well. It also doesn't have a lot of the GMail elements (chat, tags, etc), making it a rather nice distraction free way to compose email.

NOTE: You must have shortcuts enabled in your settings for this to work
