The more you click that button the faster time will go. When the main Stellarium window changes to reflect this time you can then increase the speed (if you have chosen a date/time in the past) by clicking the far right button (right-pointing double arrow) in the horizontal tool bar. In this window select the date and time you want to view. To open up the Date/Time window click to open the toolbars and then click on the button second from the top on the vertical toolbar. Time is an interesting feature in Stellarium. When the search window closes you will see that Stellarium has updated to reflect your new location. Once you have finished your location simply click the X to close the search window. The new window that opens (shown in Figure 3) is where you find your location. To open the search window open up the tool bars and click the Location button. You can search by City/State, Country, Planet, or Longitude/Latitude. To move up, down, right, or left you push and hold the Ctrl button down and then push either the up, down, left, or right arrow. What you don't see is how to move around within the window.
