 2. The content script always listens for messages being passed from the extension's target application. Upon receiving data from the target app, the content script will immediately forward this data to the background script which then updates an object called `tabsObj`. Each time `tabsObj` is updated, its latest version will be passed to Reactime, where it is processed for displaying to the user by the *app* folder scripts.
 
 3. Likewise, when Reactime emits an action due to user interaction -- a "jump" request for example --  a message will be passed from Reactime via the background script to the content script. Then, the content script will pass a message to the target application containing a payload that represents the state the user wants the DOM to reflect or "jump" to.
