Ah, I had the key bound as zle -N transpose-words-between transpose-words-about-point-match bindkey '\et' transpose-words-between with the following function (there are lots of different possible behaviours in this case). I'll find a form of words for the new standard behaviour. pws # Transpose words, matching the words using match-words-by-style, q.v. # The group of word characters preceeding the cursor (not necessarily # immediately) are transposed with the group of word characters following # the cursor (again, not necessarily immediately). # # Note the style skip-chars, used in the context of the current widget. # This gives a number of character starting from the cursor position # which are never considered part of a word and hence are always left # alone. The default is 0 and typically the only useful alternative # is one. This would have the effect that `fooXbar' with the cursor # on X would be turned into `barXfoo' with the cursor still on the X, # regardless of what the character X is. autoload match-words-by-style local curcontext=":zle:$WIDGET" skip local -a matched_words integer count=${NUMERIC:-1} neg (( count < 0 )) && (( count = -count, neg = 1 )) while (( count-- > 0 )); do match-words-by-style [[ -z "$matched_words[2]$matched_words[5]" ]] && return 1 if (( !${NUMERIC:-0} )); then # No prefix, don't advance cursor. LBUFFER="$matched_words[1]$matched_words[5]$matched_words[3]" RBUFFER="$matched_words[4]$matched_words[2]${(j..)matched_words[6,7]}" elif (( neg )); then LBUFFER="$matched_words[1]" RBUFFER="$matched_words[5]${(j..)matched_words[3,4]}\ $matched_words[2]${(j..)matched_words[6,7]}" else LBUFFER="$matched_words[1]$matched_words[5]${(j..)matched_words[3,4]}\ $matched_words[2]" RBUFFER="${(j..)matched_words[6,7]}" fi done return 0
