How do I change bash history completion to complete what's already on the line?

Question

I found a command a couple of months ago that made my bash history auto-complete on what\'s already on the line when pressing the up arrow:

$ vim fi

Update .inputrc with the following:

"\C-[OA": history-search-backward
"\C-[[A": history-search-backward

"\C-[OB": history-search-forward
"\C-[[B": history-search-forward
