/**
* Opens the currently selected file and its equivalent in the inactive folder panel if it exists.
* <p>
* This action will analyse the current selection and, if applicable, any file from the inactive
* panel that bears the same name and:
* <ul>
* <li>
* If both the selection and its inactive equivalent are browsable, both will be explored in their
* respective panels.
* </li>
* <li>
* If both are non-browsable, both will be opened as defined in {@link OpenAction}.
* </li>
* <li>
* If one is browsable an not the other one, only the current selection will be opened.
* </li>
* </ul>
* </p>
* <p>
* Note that this action's behaviour is strictly equivalent to that of {@link OpenAction} in the
* active panel. Differences will only occur in the inactive panel, and then again only when possible.
* </p>
* <p>
* This action opens both files synchronously: it will wait for the active panel file to have been
* opened before opening the inactive panel one.
