How to hide pedal markings in the engraving?

[Aron Fay]

I'm probably one of the newest members to this, so please be 
patient.

I want to submit a work to mutopia, so I've been entering music
from a very old manuscript (for piano).  No pedal markings exist 
in the original.  But, I'd like to add pedal markings, for the 
purpose of making a reasonable midi output.

I'm using a format similair to the "center dynamic" template
in the tutorial.  I've defined separate variables for the upper, 
lower, dynamics, and pedal content.  Eg:

  \context PianoStaff
  <<
    \context Staff = "up" \upper
    \context Dynamics = "dynamics" \dynamics
    \context Staff = "down" \lower 
    \context Dynamics = "pedal" \pedal
  >>
  \layout {
    % ...
  }

How can I surpress engraving of the pedal markings, but keep 
them in for midi?

Thanks,
aron
