+Operations and moves are reversed in Kakoune. First select whatever text

+Explanation: '%' selects the entire buffer, 's' opens a prompt for a
+regex, <ret> validates the regex and replace the selection with one
+per matches (hence, all occurences of word are selected). 'c' deletes
+the selection contents and enter insert mode, replacement is typed
