3.15 Case conversion

This section provides details of the commands which allow case conversions on both single words and regions of text. The three general types of case conversion are converting words to uppercase, converting words to lowercase and converting the first letter of words to uppercase.

Lowercase Word Editor Command

Arguments: None
Key sequence: Alt+L

Converts the current word to lowercase, starting from the current point. If the current point is between two words, then the next word is converted.

A negative prefix argument converts the appropriate number of words before the current point to lowercase, but leaves the current point where it was.

Uppercase Word Editor Command

Arguments: None
Key sequence: Alt+U

Converts the current word to uppercase, starting from the current point. If the current point is between two words, then the next word is converted.

A negative prefix argument converts the appropriate number of words before the current point to uppercase, but leaves the current point where it was.

Capitalize Word Editor Command

Arguments: None
Key sequence: Alt+C
