The windows above the Composer and Code Editor act as the Navigation bar. They display a list with tabs representing all currently opened Composer and Code Editor pages and permit you thus to conveniently navigate between those pages:

Navigation bar window

The Navigation bars sort all tabs chronologically according to the order in which you have opened the corresponding Composer or Code Editor pages. The last tab on the right is the recently opened Composer or Code Editor page. In case of the Navigation bar associated to the Composer, the very first tab on the left corresponds always to the project main Composer page. This is the page from which any other member within your project can be reached.

The easiest way to switch to a particular Composer or Code Editor page is to click on its corresponding tab:

The Navigation bars keep a book about the order in which you have visited the various Composer or Code Editor pages. This, in turn, permits you to navigate between the pages in a more convenient manner. In particular you can switch forth and back between the pages:

Similarly to navigate between Code Editor pages:

The above described technique navigates between the pages according to the order in which you have visited the pages. Alternatively, you can switch the pages according to the order in which the tabs are arranged:

At their both ends the Navigation bar provides small buttons to scroll its content if there is not sufficient space to display at once all currently existing tabs:

When you hold one of the buttons clicked for a period longer than 1 second, the Navigation bar continues scrolling the tabs automatically.

If during a Drag & Drop operation the mouse pointer rests over a tab for a period longer than 1 second, the Navigation bar switches automatically to the corresponding Composer or Code Editor page.

Similarly, if during a Drag & Drop operation the mouse pointer rests over the left or the right button, the corresponding button is activated and the Navigation bar scrolls its tabs accordingly. The longer the mouse pointer remains over a button the more tabs are scrolled in the Navigation bar.

These automatisms are in particular useful when you intend to perform a Drag & Drop operation between two different Composer or Code Editor pages.

Except the project main Composer page you can close any arbitrary page at any time:

If desired you can close all currently opened Composer or Code Editor pages (except the main Composer page). This is useful if you have lost the overview because of many opened pages:

If desired you can close all currently opened Composer or Code Editor pages (except the currently opened page). This is useful if you have lost the overview because of many opened pages:

Except the very first Composer tab representing the project main Composer page, you can rearrange within the Navigation Bar all other Composer and Code Editor tabs. This is useful to sort or group tabs together. For this purpose:

The Navigation bars provide a context menu with the complete list of all currently opened Composer or Code Editor pages. It permits you to explore and find the desired Composer page in a more convenient manner. This is in particular very useful, if a lot of Composer or Code Editor pages are opened:

An example of the context menu of the Navigation bar

In case of the Navigation bar controlling the Composer, the context menu groups all items automatically according to their particular affiliation. All items belonging to the same group are sorted alphabetically permitting you to find the desired Composer page more easily.

In case of the Navigation bar associated to the Code Editor, the context menu limits to sort the items alphabetically without taking in account what kind of content the respective Code Page represents.
