If you want to get Pinyin output (not just using Pinyin to get character output), you can use those cumbersome keystrokes to do so, but it's a lot of bother. An easier method is to install Biaoyin (see the .zip download on the linked page). It's still a bit annoying -- you have to keep hitting the space bar all the time -- but it's a lot easier than remembering all those key strokes.
