class Tab(Connection):
    """
    :ref:`tab` is the controlling mechanism/connection to a 'target',
    for most of us 'target' can be read as 'tab'. However it could also
    be an iframe, serviceworker or background script for example,
    although there isn't much to control for those.
    If you open a new window by using
        :py:meth:`browser.get(..., new_window=True)`
    Your url will open a new window. This window is a 'tab'.
    When you browse to another page, the tab will be the same (browser view).
    It's important to keep some reference to tab objects, in case you're
    done interacting with elements and want to operate on the page level again.

    Custom CDP commands
    ---------------------------
    Tab object provide many useful and often-used methods. It is also possible
    to utilize the included cdp classes to to something totally custom.

    The cdp package is a set of so-called "domains" with each having methods,
    events and types.
    To send a cdp method, for example :py:obj:`cdp.page.navigate`,
    you'll have to check whether the method accepts any parameters
    and whether they are required or not.

    You can use:

    ```python
    await tab.send(cdp.page.navigate(url='https://Your-URL-Here'))
    ```

    So tab.send() accepts a generator object,
    which is created by calling a cdp method.
    This way you can build very detailed and customized commands.
    (Note: Finding correct command combos can be a time-consuming task.
     A whole bunch of useful methods have been added,
     preferably having the same apis or lookalikes, as in r_selenium.)

    Some useful, often needed and simply required methods
    ===================================================================

    :py:meth:`~find`  |  find(text)
    ----------------------------------------
    Finds and returns a single element by text match.
    By default, returns the first element found.
    Much more powerful is the best_match flag,
    although also much more expensive.
    When no match is found, it will retry for <timeout> seconds (default: 10),
    so this is also suitable to use as wait condition.

    :py:meth:`~find` |  find(text, best_match=True) or find(text, True)
    -----------------------------------------------------------------------
    Much more powerful (and expensive) than the above is
    the use of the `find(text, best_match=True)` flag.
    It will still return 1 element, but when multiple matches are found,
    it picks the one having the most similar text length.
    How would that help?
    For example, you search for "login",
    you'd probably want the "login" button element,
    and not thousands of scripts/meta/headings,
    which happens to contain a string of "login".

    When no match is found, it will retry for <timeout> seconds (default: 10),
    so this is also suitable to use as wait condition.

    :py:meth:`~select` | select(selector)
    ----------------------------------------
    Finds and returns a single element by css selector match.
    When no match is found, it will retry for <timeout> seconds (default: 10),
    so this is also suitable to use as wait condition.

    :py:meth:`~select_all` | select_all(selector)
    ------------------------------------------------
    Finds and returns all elements by css selector match.
    When no match is found, it will retry for <timeout> seconds (default: 10),
    so this is also suitable to use as wait condition.

    await :py:obj:`Tab`
    ---------------------------
    Calling `await tab` will do a lot of stuff under the hood,
    and ensures all references are up to date.
    Also it allows for the script to "breathe",
    as it is oftentime faster than your browser or webpage.
    So whenever you get stuck and things crashes or element could not be found,
    you should probably let it "breathe" by calling `await page`
    and/or `await page.sleep()`.

    It ensures :py:obj:`~url` will be updated to the most recent one,
    which is quite important in some other methods.

    Using other and custom CDP commands
    ======================================================
    Using the included cdp module, you can easily craft commands,
    which will always return an generator object.
    This generator object can be easily sent to the :py:meth:`~send` method.

    :py:meth:`~send`
    ---------------------------
    This is probably the most important method,
    although you won't ever call it, unless you want to go really custom.
    The send method accepts a :py:obj:`cdp` command.
    Each of which can be found in the cdp section.

    When you import * from this package, cdp will be in your namespace,
    and contains all domains/actions/events you can act upon.
