Is there a shortcut use for "Insert a line above current line"?

[wtfisgoingoff]

I found shift+Enter "insert new line" in Edit->special commands->other.
And there is no "insert new line above current line" in keyboard plugin.(This is very convenient！！！)
Is it possible that I add this function to keyboard plugin or is there another plugin could do this ?

Thx

Nope, you'll have to modify the cbEditor class if you have the desire.
But what is the purpose of this command? Just do one up-arrow+ctrl-enter to do the same.
