The ribbon area

The ribbon area contains all the tools and commands properly arranged into different tabs and panels. Home, Insert, Annotate, Parametric, and so on are the tabs in which different panels are placed in a meaningful order. For example, the Home tab contains the Draw and Modify panels, which in turn contain most of the frequently used commands:

Similarly, other less frequently used panels and subsequently, the commands, are in other tabs, such as the Parametric or Express Tools tabs, which are other tabs found in the ribbon area.

The panels and tabs are not permanent and you can hide or reveal them by simply right-clicking on any panel. To hide or show any tab, just right-click on any panel and go to the Show Tabs option. Then, check the tab that you want to show; or similarly, to hide any tab, repeat the same process and uncheck the tab from the right-hand side context menu:

To hide or show any panel of a tab, just go to the tab and right-click on any of its panels, then right-click and go to the Show Panels option and check or uncheck the panels that you want to show or hide.
