I'd love to see an IDE that actively taught keyboard shortcuts as you used it. For instance, let's say you used the mouse to click a save-icon or use the File menu to save a file. I'd like to see the IDE pop up an alert, change some text or otherwise inform the user that "Hey - control-S is the keyboard shortcut to do what you just did." Basically, I want the IDE to actively guide me towards more productive ways to use it instead of just making me refer to a help file or discover those ways on my own. I saw something like this on a presenter's laptop at a conference once a long time ago, and the brilliance of it didn't strike me until later on.
