Codio has keyboard shortcuts and they can all be customized. We are also adding a sublime like command bar and many other productivity focused features. We are adding a load of stuff for back-end development, too.
Codio is a complete, fully functional IDE, not a Codepen clone. We also have a lot of server side stuff coming out next week and server side support is an ongoing thing, as is offline editing, which will be coming out Q1 next year. We're still in Beta so we're listening hard!
