# Transpose words, matching the words using match-words-by-style, q.v.
|
|
# The group of word characters preceding 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.
