Restarting level in Super Meat Boy

Is there a key to restart a level in Super Meat Boy?

Other than going back to level select and selecting it again, I mean.

(I'm playing it on OSX/Steam, in case this matters)

There is no restart in Super Meat Boy other than killing yourself, or even finishing the level which will prompt you if you want to re-try the level. With how fast the game can load, however, this is almost as quick, if not, faster than any other game's restart.

You can restart the level by choosing a new character. For example if you're playing as meat boy, switch character to Commander Video and the level resets.

I'm not sure if it does this when switching from one character to the same, i.e. meat boy to meat boy.
