I am pretty mouse-averse, and I find a nice solution to these sorts of
interactive-selection problems is to use your editor. In its most basic
form, something like:

  git log --oneline >tmp
  $EDITOR tmp ;# and delete everything you don't want
  git cherry-pick `cat tmp`

assuming you are proficient with your editor, finding the entry you want
and deleting all of the unwanted lines should be just a few keystrokes.
And you can simplify it with a script like this:

  $ cat `which vpipe`
  #!/bin/sh
  trap 'rm -f $tmp' 0
  tmp=`mktemp vpipe-XXXXXX` &&
  cat >$tmp &&
  ${EDITOR:-vi} $tmp </dev/tty >/dev/tty &&
  cat $tmp

which you can then use like:

  git cherry-pick `git log | vpipe`

I know that sort of thing is not for everyone (you have to really like
your editor), but I thought I'd share in case it is useful.
