Any command other than an undo command breaks the sequence of undo
commands. Starting from that moment, the entire sequence of undo
commands that you have just performed are themselves placed into the
-undo record, as a single set of changes. Therefore, to re-apply
-changes you have undone, type @kbd{C-f} or any other command that
-harmlessly breaks the sequence of undoing; then type @kbd{C-/} to undo

+@kbd{C-f} or any other command that harmlessly breaks the sequence of
+undoing; then type @kbd{C-/} one or more times to undo some of the
+undo commands.
Alternatively, if you want to resume undoing, without redoing
previous undo commands, use @kbd{M-x undo-only}. This is like
dragging the word preceding or containing point forward as well. The
punctuation characters between the words do not move. For example,
@w{@samp{FOO, BAR}} transposes into @w{@samp{BAR, FOO}} rather than
-@samp{@w{BAR FOO,}}.
+@samp{@w{BAR FOO,}}. When point is at the end of the line, it will
+transpose the word before point with the first word on the next line.
@kbd{C-M-t} (@code{transpose-sexps}) is a similar command for
transposing two expressions (@pxref{Expressions}), and @kbd{C-x C-t}
