13.3 Case Conversion

M-- M-l

Convert last word to lower case. Note that 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 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 do not move the cursor when used with a negative argument. As soon as you see you have mistyped the last word, you can simply case-convert it and continue typing. See Case.
