You don't need that step - that was him finding out what buttons were which. What TV do you have? You just write your remote.xml and put it in the keymaps folder. e.g. mine for samsung that I just got off someone on the internet - i was only really bothered about having access to home, movies and tv shows by one button as everything else I wanted worked straight away.
Code:
<keymap>
<global>
<remote>
<teletext>XBMC.ActivateWindow(Home)</teletext> <!--PRE-CH -->
<red>ContextMenu</red>
<green>Info</green>
<yellow>XBMC.ActivateWindow(VideoLibrary,MovieTitles)</yellow>
<blue>XBMC.ActivateWindow(VideoLibrary,TvShowTitles)</blue>
<title>XBMC.ActivateWindow(Favourites)</title> <!--FAV.CH-->
</remote>
</global>
<FullscreenVideo>
<remote>
<pageplus>NextSubtitle</pageplus><!--channelup-->
<pageminus>AudioNextLanguage</pageminus><!--channeldown-->
<select>OSD</select>
<red>OSD</red>
<green>Info</green>
<yellow>CodecInfo</yellow>
<blue>OSD</blue>
<teletext>AspectRatio</teletext> <!--PRE-CH -->
<back>XBMC.ActivateWindow(Home)</back> <!--exit-->
</remote>
</FullscreenVideo>
</keymap>
