Question

In XCode there's a really neat feature called "Kill Ring" which I get a hint what its about here but I don't know how to use it!!

How do you use the "Insert Kill Ring" feature in XCode?

Answer 1

If the article Customizing the Cocoa Text System has anything to do with it, then it states:

“kill ring” which large deleted blocks of text get copied to

NSTextKillRingSize apparently sets the size of the kill ring.

Please read the above article, you'll probably understand it better than me.
