In some editors, if you press while in the middle of the last line, it takes you to the end of the line (or, equivalently, the document). I have grown somewhat used to this. How do I obtain the same behaviour in Vim?

This seems to do what you want:

:noremap <expr> <Down> line('.') == line('$') ? '$' : 'j'
  • We use the <expr> keyword to tell Vim to expect an expression, and use the value of that.
  • line('.') gets the current line number, line('$') gets the last line number

For insert mode, you can use a slightly different version:

:inoremap <expr> <Down> line('.') == line('$') ? '<End>' : '<Down>'

This uses <End> and <Down>, rather than $ and j (actually, those will work in noremap as well).

  • Dammit I forgot to mention that I'd like it for insert mode too. I suppose that can be handled by an imap with <ESC> prepended and a appended?

  • @muru I would say that using <Down> and <End> is easier ;-) See updated answer. Mar 15, 2015 at 6:32

    Whitespace is totally valid in the right-hand-side of an <expr> mapping. You might be thinking of :set?
