from the readline manual:

       To  find other matching entries in the history list, type C-s or C-r as
       appropriate.  This will search backward or forward in the  history  for
       the  next  line matching the search string typed so far.  Any other key
       sequence bound to a readline command will terminate the search and exe‐
       cute  that  command.  For instance, a newline will terminate the search
       and accept the line, thereby executing the  command  from  the  history
       list.  A movement command will terminate the search, make the last line
       found the current line, and begin editing.

It appears that C-s and C-r are the only keybindings that are accepted in
an incremental search, i.e. they are not configurable.
