Page up history-search-backward inputrc

Well I have been forced to use ubuntu for a while. Because openSuse 11.0 only has svn 1.5 and it is not compatible with the svn servers here at work. So I have had to figure out how to do some things in ubuntu. One is getting the pageup key to walk backward thru the history like it did in Suse. So I found this in the /etc/inputrc file.
I uncommented out the alternate mapping of \e[5 to do history-search-backward. That is all there is to it.
