Internet Explorer 10 comes in two different versions: the minimalist Modern UI/Metro version accessed from the Start screen and the traditional, full-featured Desktop version accessed from the Taskbar.
The Modern UI/Metro version of IE10 offers two app bars.
(1) The bottom bar is called the Navigation bar and it includes the Back button, Site icon, Address bar, Refresh/Stop button, Pin to Start/Jump List button, Page tools button, and Forward button.
(2) The top bar is called the Tab Switcher and displays thumbnails of open tabs and the New Tab and Tab Menu buttons. The Tab Switcher bar allows you to switch tabs, open a new tab, close existing tabs, and open a new InPrivate tab.
(3) Both bars are hidden while surfing the web, but they can be displayed by pressing Windows key + Z or right-clicking on a web page (not on a link).
(4) To open only the Navigation bar and select the contents of the Address box, press F4 or Alt + D.
(5) The currently active tab is indicated on the Tab Switcher bar with a blue border. Activate a non-active tab by clicking on the desired tab on the Tab Switcher bar.
(6) To close a tab, click the X button in the upper, right corner of the tab thumbnail on the Tab Switcher bar.
(7) If you prefer to use the keyboard, you can press Ctrl + W to close the currently active tab, Ctrl + Tab to scroll forward among the tabs, Ctrl + Shift + Tab to scroll backward among the tabs, Ctrl + K to duplicate the currently active tab, and Ctrl + Shift + T to reopen the last closed tab
(8) The + button opens a new tab, activates the Navigation bar, puts the cursor in the Address box, and displays Pinned and Frequent site tiles.
(9) Click the (…) button to display a popup menu allowing you to open a new InPrivate tab or to close all tabs except for the currently displayed tab. (10) If only one tab is open, the Close tabs option is grayed out.
(11) When the Address box on the Navigation bar is activated, Pinned and Frequent site tiles display above the Address box.
(12) Click any tile to open the site in the current tab. Right-click on a tile to either open it or remove it from the list. You can also Shift + Click to open a site in a new tab.
(13) The Modern UI/Metro version of IE10 cannot have multiple windows open, but it supports having up to 10 tabs open at a time.
(14) To open a webpage from a link in a new tab and switch to the new tab immediately, hold down the Ctrl and Shift keys and click on the link.
(15) To open a webpage from a link in a new background tab and leave the currently open tab active, hold down just the Ctrl key while clicking on the link.
(16) You can also open a link in a new background tab by right-clicking on a link and selecting Open link in new tab.
(17) When clicking links in Address bar search results, use Shift + Click to open a link in a new tab and bring focus to that tab and Ctrl + Click to open a link in a background tab but keep the current tab active.
(18) Use Shift + Click to open links from Pinned or Frequent site tiles in a new tab and bring focus to that tab.
Just like the Desktop version of IE10, each tab in the Modern UI/Metro version of IE10 has its own browsing history. If one tab crashes, all other tabs and IE10 itself continues to work normally. You can have the Modern UI/Metro version of IE10 open the tabs from the last session the next time you open the browser.
