In my Vimscript program, I need to open an additional Vim buffer that is not immediately associated with a file, but which the user can save to a file of her/his choosing, just like the initial buffer called [No Name]. How can I do this?
There are many ways to open a new buffer with no name, the simplest of which is :new.
:new will create a split window with an unnamed buffer.
:enew will open one in the current window.
:vnew will open one in a vertically split window.
:tabnew will open one in a new tab.
