21.3 Case Conversion
- M-- M-l
- Convert last word to lower case. Note Meta-- is Meta-minus.
- M-- M-u
- Convert last word to all upper case.
- M-- M-c
- Convert last word to lower case with capital initial.
A very common error is to type words in the wrong case. Because of this,
the word case-conversion commands M-l, M-u and M-c have a
special feature when used with a negative argument: they do not move the
cursor. As soon as you see you have mistyped the last word, you can simply
case-convert it and go on typing. See Case.
