The Fixture Code for ActionFixtures[?]

Here is our example test table from the ActionFixture page:

Action Fixture.
start	fitnesse.fixtures.CountFixture
check	counter	0
press	count
check	counter	1
press	count
check	counter	2
enter	counter	5
press	count
check	counter	6

And here is the code for the CountFixture:

public class CountFixture extends Fixture {
  private int counter = 0;

  public void count() {
    counter++;
  }

  public int counter() {
    return counter;
  }
} 

As you can see, the names of the buttons (check, press, and enter) and registers (count and counter) correspond directly to methods in the 'started' fixture. And the meter values (the numbers in the rightmost column) are returned by the counter() method. It's really as simple as that.
