2.3.6 Case Modification Commands

Hemlock provides a few case modification commands, which are often useful for correcting typos.

Command: Capitalize Word (bound to M-c) ¶

Command: Lowercase Word (bound to M-l) ¶

Command: Uppercase Word (bound to M-u) ¶

These commands modify the case of the characters from the point to the end of the current or next word, leaving the point after the end of the word affected. A positive prefix argument modifies that many words, moving forward. A negative prefix argument modifies that many words before the point, but leaves the point unmoved.

Command: Lowercase Region (bound to C-x C-l) ¶

Command: Uppercase Region (bound to C-x C-u) ¶

These commands case-fold the text in the region. Since these commands can damage large amounts of text, they ask for confirmation before modifying large regions and can be undone with Undo.
