To run direct:

1. Fire an event named "a"; then fire an event named "b".

To run variable:

1. Fire an event named name.

To run text only:

1. At this point scripts may run. At this point scripts may run.

2. At this point scripts may run in example only.

To run other text:

1. At this point scripts may run.

To run a text definition:

1. Let A be the following steps:

   1. Perform a text-only checkpoint.

2. Queue a microtask, given A.

To run same segment:

1. Queue a microtask to fire an event named "a".

To run caller R:

1. Let A be the following steps:

   1. Fire an event named "a".

2. Queue a microtask, given A.

To run caller S:

1. Let B be the following steps:

   1. Fire an event named "b".

2. Queue a microtask, given B.

To run cycle R:

1. Run cycle S.

To run cycle S:

1. Run cycle R, then fire an event named "a".

To run unknown timing:

1. Let A be the following steps:

   1. Fire an event named "a".

2. Consume these steps, given A.

To run mention:

1. See the fire an event algorithm for background.

To run host caller:

1. Call the host operation.

To run host implementation:

1. Queue a microtask.

To run nested context:

1. Return.

2. If the document is active, then:

   1. Fire an event named "a".

To run clipped context:

1. If this deliberately long condition xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx holds, then:

   1. Fire an event named "a".
