Answer Key

Browser function: multiple tabs

Section A: Quick Questions

A — Keep several web pages open at once in one window

A — Open a new tab

B — Click the tab for the page you want

A — Many pages can be open in one window

B — Open the video in a new tab and switch between the two

Section B: Match the Pairs

Ctrl + T → Opens a new tab so another web page can be loaded in the same browser window

Ctrl + Tab → Switches to the next open tab without closing or reloading the pages

A browser keeps many pages open in one window using tabs → Window 1: Tab 1 = school-email, Tab 2 = news, Tab 3 = revision-notes

Switching tabs lets you move between open pages and keep your place → click Tab 2 -> show news page, Tab 1 stays open

To read a second page, close the first tab and then open a new one → Tabs let you keep the first page open. You do not need to close it, so you would lose your place for no reason.

Each tab needs its own separate browser window → Tabs share one window. Several tabs sit in a single browser window, so no extra windows are needed.

Section C: Definitions

multiple tabs — A browser feature that keeps several web pages open at once in one window, so you can open a new tab and switch between pages without losing your place.

Section D: Fill in the Blanks

<a href="news.html" target="_blank">Go</a>

window.open("news.html", "_blank");

let tabs = ["Maths", "News"];
tabs.push("Mail");

<a href="news.html" target="_blank">Go</a>

Section E: Spot the Error

B — closeTab removes a page. To open another page in the same window you need window.openTab("bbc.com").

D — The text and the variable must be joined with &. It should be OUTPUT "Tabs open: " & tabs.

C — The closing bracket is missing. It should be window.switchTo("news.com") to move back to the news tab.

B — A window with many tabs needs a list to hold many pages. A single empty string holds no list. It should be window.tabs ← [].

A — An IF statement must end its condition with THEN. It should be IF key = "Ctrl+T" THEN.
