Blank Lines
Here are special commands and techniques for putting in and taking out
blank lines.
- C-o
- Insert one or more blank lines after the cursor (
open-line).
- C-x C-o
- Delete all but one of many consecutive blank lines
(
delete-blank-lines).
When you want to insert a new line of text before an existing line, you
can do it by typing the new line of text, followed by <RET>.
However, it may be easier to see what you are doing if you first make a
blank line and then insert the desired text into it. This is easy to do
using the key C-o (open-line), which inserts a newline
after point but leaves point in front of the newline. After C-o,
type the text for the new line. C-o F O O has the same effect as
F O O <RET>, except for the final location of point.
You can make several blank lines by typing C-o several times, or
by giving it a numeric argument to tell it how many blank lines to make.
See Arguments, for how. If you have a fill prefix, then C-o
command inserts the fill prefix on the new line, when you use it at the
beginning of a line. See Fill Prefix.
The easy way to get rid of extra blank lines is with the command
C-x C-o (delete-blank-lines). C-x C-o in a run of
several blank lines deletes all but one of them. C-x C-o on a
solitary blank line deletes that blank line. When point is on a
nonblank line, C-x C-o deletes any blank lines following that
nonblank line.
