In the on Tuesday, Rob Mauceri, group program manager for Internet Explorer, explains the changes to IE10 and how the Metro interface is different. The new additions can be broken down into these three categories.
1. Metro Styling
The first thing apparent in IE10's Metro interface is that the browser fills your entire screen, "edge-to-edge", and though a navigation bar appears at the bottom of the screen when you first open the app, it disappears when not needed. Without visible controls on the screen, new users will take some time to learn how to navigate.
Touch-friendly gestures such as swiping left or right work on touch-capable devices, but those with a mouse and a keyboard will find the interface less intuitive. Moving towards the left or right edges of the screen with a mouse reveals arrows equivalent to the forward and previous page commands in most browsers.
Right-clicking reveals the navigation bar on the bottom of the screen, necessary for typing in a new URL, and it displays any open tabs or windows at the top of the screen, providing the ability to switch between them. When typing a URL, "Navigation Tiles" appear that show frequently visited sites and those you've previously pinned to the Start screen. The tiles are filtered as you type, providing a way to click or tap a site after only a few keystrokes.
