If your system lacks touch, you will need to use your mouse to emulate touch commands. Problem is, the mouse isn't really a one-for-one substitute: Flicking, for example, is impossible to execute with a mouse. Mouse movements are also used to expose functionality like the app switcher or charms bar, by flicking the cursor to a corner of the screen -- all the more difficult when using multiple monitors. Windows 8 offers new keyboard shortcuts to access features and settings, but utilities with Win-key combinations will likely override these shortcuts or make them behave strangely. Press Win-C to open the charms bar no matter what system context you're in (pictured). The resulting menu can be browsed using the arrow keys.
