Message Footer

Is it possible to change the footer that is written on each message?
Currently the footer provides links to Prev by Date,
Next by Date, Previous by thread, Next by thread, Indexes(es)..Date and
Thread.  Where are the controls for this footer?  I would like to only
show the indexes and change the text.
 
For example...instead of

*       Index(es):

*       Date
*       Thread

I would like to read
 
    Sorted by Date
    Sorted by Subject
 
Thanks
 
btw  I am using version 2.5.13 on Win2k
