Need help playing GCN games without controllers

[R492]

Hello all, I'm a recent downloader of the Dolphin emulator and while it runs great I ran into a minor snag.  I don't own any controllers and was hoping there were some way to play using only a keyboard?  If not I do also have a PS3 controller but I'd rather not use it if possible.

Yes, you can use a keyboard. The controls are actually mapped to the keyboard by default.
