During my journey through layout-land, I've gotten the weird idea of also learning a one-handed layout, just to be able to type with one hand, while operation the mouse with the other.
I've decided to learn Dvorak one-handed ones first; since the they are rather mirrored, learning one more or less also teaches you the other. But what i wonder now is this: How am I supposed to put my fingers on there?

For both, I guessed I had to place my index finger on E and pinky on D. Tell me if I'm wrong. Also tell me if you think of better one-handed inputs, for occaisonal left/right-handed typing.
Maybe learning to type your default layout (be it QWERTY or Colemak) with one hand, isn't such a bad idea..
