"C-h k C-x C-o" tells me that


C-x C-o runs the command delete-blank-lines, which is an interactive
compiled Lisp function in `emacs/lisp/simple.el'.

It is bound to C-x C-o.

(delete-blank-lines)

On blank line, delete all surrounding blank lines, leaving just one.
On isolated blank line, delete that one.
On nonblank line, delete any immediately following blank lines.
