What is the purpose of the transition ribbon and feature in microsoft powerpoint?

When you open a PowerPoint document, the ribbon appears as a row of labels, or what we call tabs.

When you go to a tab, the ribbon for that tab opens and you can see the tools and functions that were formerly in menus and toolbars in earlier versions of PowerPoint.

When you see a feature with an arrow   , you can click it to get more information or options.

You might also notice launchers   at the corner of some of the ribbon’s groups – like in the Clipboard and Font groups. Click those to open the dialog box related to that function – the launcher on the Font group, for example, opens the Font box, where you set effects such as strikethrough, superscript, or character spacing.
