In this chapter we describe commands that are useful when you catch a mistake while editing. The most fundamental of these commands is the undo command
C-/ (also bound to
C-x u and
C-_). This undoes a single command, or a part of a command (as in the case of
query-replace), or several consecutive character insertions. Consecutive repetitions of
C-/ undo earlier and earlier changes, back to the limit of the undo information available.
Aside from the commands described here, you can erase text using deletion commands such as
delete-backward-char). These were described earlier in this manual. See Erasing.
