@chapter Commands for Fixing Typos

In this chapter we describe commands that are useful when you catch
-a mistake while editing. The most fundamental command for correcting
-erroneous editing is the undo command @kbd{C-/} (which is also bound
-to @kbd{C-x u} and @kbd{C-_}). This undoes a single command, or a

+This undoes a single command, or a
part of a command (as in the case of @code{query-replace}), or several
consecutive character insertions. Consecutive repetitions of
@kbd{C-/} undo earlier and earlier changes, back to the limit of the
The @dfn{undo} command reverses recent changes in the buffer's text.
Each buffer records changes individually, and the undo command always
applies to the current buffer. You can undo all the changes in a
-buffer for as far as back its records go. Usually, each editing
+buffer for as far back as the buffer's records go. Usually, each editing
command makes a separate entry in the undo records, but some commands
such as @code{query-replace} divide their changes into multiple
entries for flexibility in undoing. Consecutive character insertion

also bound to @kbd{C-x u} because that is more straightforward for
beginners to remember: @samp{u} stands for ``undo''. It is also bound
-to @kbd{C-_} because typing @kbd{C-/} on some text-only terminals
-actually enters @kbd{C-_}.}. This undoes the most recent change in
-the buffer, and moves point back to where it was before that change.

changes have already been undone, the undo command signals an error.
