In addition to the regular vertical motions, I use a modified version of http://stackoverflow.com/questions/4946421/vim-moving-with-hjkl-in-long-lines-screen-lines. I usually move with the arrow keys, not hjkl (looong time user of other editors before I found Vim, too used to arrows/Home/end/PgUp/PgDn to switch, even after 5+ years of exclusive Vim use).
return "g" . a:movement
map <expr> <C-Down> ScreenMovement("j")
map <expr> <C-Up> ScreenMovement("k")
map <expr> <C-Home> ScreenMovement("0")
map <expr> <C-End> ScreenMovement("$")
By holding Ctrl I can go visually to start/end of or up/down display rows. For me this is more efficient than the alternatives, at least.
Almost forgot: I needed to modify .Xdefaults for it to work in specifically urxvt, but that is probably an off-topic issue (with answers on Google).
