Answer 1

Rhubarb's answer is correct and works but one thing, there is more simple command in plist file. Follow all instructions of Rhubarb's but

instead of

moveToEndOfLine:, deleteToBeginningOfLine:, deleteToEndOfParagraph:

use below

selectLine:, delete:

This is more clear and throw away any possibility of malfunction.

I want to write this as a comment, but my "reputation" doesn't allow me to do that.
