Vim mouse wheel vertical scrolling just one line

Question

How do I need to adjust my vimrc to make vertical scrolling smoother? I want to achieve that one iteration of the mouse wheel just scrolls one instead of three lines.

Answer 1

try adding this into your vimrc:

   map <ScrollWheelUp> <C-Y>
   map <ScrollWheelDown> <C-E>

P.S. the best solution would be: don't use that mouse-wheel...
