Tabs in a GUI window. Use the whitespace, text-formatting, or CSV tags if your question involves the tabulation (tab) character.

A tab is a panel in a window, tyipcally chosen via a row of labels at the top (or sometimes a column of labels on the side). For example, many web browsers support multiple tabs in the same window, each showing one web page and having its own history.
