Synchronous Vs. Asynchronous Events

Some event handlers are called immediately when the event occurs. These are called ‘synchronous’ events. An example is DocumentNew. It gets called as soon as the user creates a new document.

However, some events are called shortly after the event occurs, usually after a short amount of idle time. These are called ‘asynchronous’ events. They are asynchronous because it would destabalize Source Insight if a user-written macro were to be called at the exact time the event occured.
