我使用以下代码片段，可以帮助所有形式的导航，包括$到行尾等。
" mapping to make movements operate on 1 screen line in wrap mode
function! ScreenMovement(movement)
if &wrap
return "g" . a:movement
else
return a:movement
endif
endfunction
onoremap <silent> <expr> j ScreenMovement("j")
onoremap <silent> <expr> k ScreenMovement("k")
onoremap <silent> <expr> 0 ScreenMovement("0")
onoremap <silent> <expr> ^ ScreenMovement("^")
onoremap <silent> <expr> $ ScreenMovement("$")
nnoremap <silent> <expr> j ScreenMovement("j")
nnoremap <silent> <expr> k ScreenMovement("k")
nnoremap <silent> <expr> 0 ScreenMovement("0")
nnoremap <silent> <expr> ^ ScreenMovement("^")
nnoremap <silent> <expr> $ ScreenMovement("$")
