I can think of two things. First, bash offers tab-completion. If you
type the first few keystrokes of a command and hit tab, bash will
attempt to complete it for you. It takes some getting used to, but you
might find it easier than arrowing through your bash history.
Also, you could write a script that trims duplicates from your
~/.bash-history at shell startup-
Oh, actually you can edit ~/.bashrc and enable the option to ignore
duplicates in bash-history.
The relevant lines look like this:
# don't put duplicate lines in the history. See bash(1) for more options
# don't overwrite GNU Midnight Commander's setting of `ignorespace'.
# ... or force ignoredups and ignorespace
