;; The target buffer can be changed with `reb-change-target-buffer'
;; ("\C-c\C-b"). Changing the target buffer automatically removes
;; the overlays from the old buffer and displays the new one in the
;; target window.
;; The `re-builder' keeps the focus while updating the matches in the
;; target buffer so corrections are easy to incorporate. If you are
;; satisfied with the result you can paste the RE to the kill-ring
