How can I delete a line without putting it into my default buffer?

Example:

line that will be copied.

line that I want to be substitued with the previou         


        

Answer 1

Use the "black hole register", "_ to really delete something: "_d.
Use "_dP to paste something and keep it available for further pasting.

For the second question, you could use dw. is used to execute a normal command without leaving the insert mode.

You can setup your own mappings to save typing, of course. I have these:

nnoremap d "_d
xnoremap d "_d
xnoremap p "_dP
