Since the default values are displayed in a special format
using an arrow

  Query replace (default from1 -> to1): 

a history navigation key should bring the pair into the minibuffer
in the same format like

  Query replace (default from1 -> to1): from2 -> to2

Then the user has to be careful to not remove the arrow
while editing the inserted values in the minibuffer.

Another problem is how to parse such format
when a from/to value contains the arrow "->"

  Query replace (default from1 -> to1): from2 -> from2 -> to2 -> to2
