Drafting up an attempt at keyboard support for the playground, on the Vera side:

The primitive, I think, at least for game-style programs (actively rendering and polling state), should be a set of counters as below:

Key a is pressed
Key b is pressed
...
Key shift is pressed
Key space is pressed

Then, edge-triggered behaviors can be handled like so

| check key a, Key a is pressed, Key a was pressed | 
    Key a is pressed, Key a was pressed
| check key a, Key a is pressed | 
    Key a was pressed, Key a was just pressed
| check key a, Key a was pressed | 
    Key a was released
