8.7 Blank Lines
Here are special commands and techniques for inserting and deleting 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
).
To insert a new line of text before an existing line,
type 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 specifying how many blank lines to make. See section Numeric Arguments, for how. If you have a fill prefix, the C-o command inserts the fill prefix on the new line, if typed at the beginning of a line. See section The 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
lone blank line deletes that one. When point is on a nonblank line,
C-x C-o deletes all following blank lines (if any).
