Interesting idea, but it's rather odd that the keystroke for P is pressing <SPACE>, but the keystroke for <SPACE> is a four character combination when <SPACE> should be its own chord. While the binary incrementing keystroke combination is somewhat logical, I would imagine that a more frequency-based assignment would ultimately be more successful as muscle memory is far more important than remembering that the chord for V is binary+1 of the chord for U.
