Thanks for your advice, but misteriously, it is back to normal now.
I swear to god I didn't do anything, oh, wait, maybe I did  an aptitude 
upgrade
without even knowing about it.

BTW, I wasn't talking about the default bash key binding.
I don't know the official name, it works like this:
enter a word, say "cd" in a bash shell, then press
up and down key will walk you through all previous commands
that start with "cd" one by one. This is more efficient
than the default behavior of up/down key binding, which
shows you the whole command history one by one.
