I've watched the video on that page many times and I'm still
trying to figure out what kind of problem this module can solve
that cannot be solved with history search, menu completion and
pressing <TAB> a couple of times.

The multi-word matching syntax would be helpful in general for all
"search"-type operations.

I never use the mouse for that (partially because the middle mouse
button is broken):

  (Move cursor to start of word to copy)
  Ctrl-Space (set mark)
  (Move cursor to start of word to copy)
  Ctrl-w (cut)
  (Move cursor to new location of the word)
  Ctrl-y (yank; insert cut buffer)

Or with the example from the video:

  # type
  mplayer -fs
  # noticed that I need a long word from the history, so comment
  # out the unfinished command line and store it in the history
  # look for the history line with the long word; the multi word
  # search would be helpful
  # Mark and cut the file name:
  <move cursor><ctrl-space><ctrl-f><ctrl-w>
  # abort editing
  # recall the unfinished command and insert the cut-buffer
  <cursor-up><ctrl-e> <ctrl-y>
  # remove comment and execute

That's fifteen additional keystrokes plus typing part of the file
name and moving the cursor to the start of the name.  And that's a
lot more typing than just "mplayer -fs The_Voi<TAB><RETURN>".

To me it appears that cases where a complicated part of a former
history line needs to be copied and the same cannot easily be done
with completion is quite rare.  And even then I could just edit
the complicated line instead of copying a part of it to a new

I'm really interested in user experience with that approach,
