Even better, the CharmsBar and toggle-trigger on the left side of the screen are both within thumbs reach, so it's easy to move through the OS while still cradling your tablet in a natural position.
The same gestures apply -- swiping in from the right to expose the CharmsBar, swiping from the left to toggle through open programs and swiping the bottom or top of the display to expose settings specific to a certain application.
If you're less in the mood to meander and more in the mood to find something specific, you can search in one of two ways: you can swipe the CharmsBar and select the Search option, or you can just start typing.
