Vim split line command

In vim, J joins the next line to the current line. Is there a similar one-key (or relatively short) command to split a line at a given cursor position? I know it be done with a simple macro, but it seems like if the J-command exists there should be a similar function. I've tried searching for it, but can't seem to find an answer.

rEnter while on whitespace will do it. That's two keystrokes.

I don't think that there is a single key command for this. The best you can do with stock vim is probably i Enter Esc.

My solution was to remap the K key since I never use the default action (look up the word under cursor with "man"), and my previous editor used Alt+j and Alt+k to join and split lines, respectively.

:nnoremap K i<CR><Esc>

This rolls those three annoying keystrokes into one.

There's probably a more sophisticated way to also eliminate any trailing whitespace, but I prefer to strip all trailing whitespace on write.

No. I've now read enough answers to conclude that there is no such command.

Easy answer: Pressing 'Enter' while in insert will do it; but you're right, there oughtta be a key for it in command mode. I've wondered, too.

Since everyone has a favorite workaround, I will share mine. The assumption is that I will do anything to avoid having to reach for the Esc key.

ylprX ... where 'X' is the inserted character, which can even be a newline.

So, 'yl' is yank on char to the right, 'p' = paste the char, 'r' is replace that char; then you just type the new char. That's how much I hate using Escape.

(That was 'l', as in "move right", BTW)

Old thread, but I dont use "K" for the man page lookup or whatever magic it does. So I have this mapping in my .vimrc:

map K i<Enter><Esc>

I figured since "J" is join, "K" can be krack or something. :)

You can split lines if you can create a regular expression for the location to add the split. For example if you want to split the lines at each semicolon, you can use the following substitution:

%s/;/^v^m/g

to great effect

Jed's answer is most useful. I would like to add that I needed the "control-V-alternative", i.e. control-Q: %s/;/^q^m/g
