If you edit a command in your history and then execute a different
one, the edited command remains in your history.  For example, the
sequence <up>^a^k<down><enter> (where ^a means control-a) erases the
previous command from my history (although it puts it in my kill ring,
but that's not so dangerous.

You can also use ^r to search for something specific; I use this if
I'm going back more than few commands.  Read the history section of
the bash man page for more fun tricks.
