Keys 1-5 are your frets (more frets for higher difficulty).
Enter is your strum bar.
Set up an account and you can play against friends/other users, gain xp, get achievments...
The track listing is full of fairly unknowns but everything is well suited to a Guitar Hero-ing.
Presentation and execution is spot on.
