To change the keybinds, you first need to locate your SMB folder.

Go to your library, and rightclick on supermeatboy.
Then hit properties.
Go to "Local Files" and hit the top button. (Don't know what it says in english, somethign about looking trough files)

It should open the super meatboy folder inside your steam folder.

In there sould be a file called "buttonmap.cfg"
Open it with a programm like Notepad++.
There you can change your Keybinds.
