2.3.8 Whitespace Manipulation

These commands change the amount of space between words. See also the indentation commands in section indentation.

Command: Just One Space (bound to M-|) ¶

This command deletes all whitespace characters before and after the point and then inserts one space. If a prefix argument is supplied, then that number of spaces is inserted.

Command: Delete Horizontal Space (bound to M-\) ¶

This command deletes all blank characters around the point.

Command: Delete Blank Lines (bound to C-x C-o) ¶

This command deletes all blank lines surrounding the current line, leaving the point on a single blank line. If the point is already on a single blank line, then that line is deleted. If the point is on a non-blank line, then all blank lines immediately following that line are deleted. This command is often used to clean up after Open Line.
