Vim find last occurrence of

An easy way to find the last occurrence is to jump to the end and search backwards:

G?foo<CR>

In fact, there's an even easier way if you were already searching for something. Just jump to the end and search backwards for the thing you were just searching for:

GN

Simple as that.

Edit: if your search occurred on the very last line, then GN would skip over it to the second last occurrence. Using ggN would solve this problem. (And gg?foo<CR> for similar reasons.)

A potentially longer solution:

:vim foo % | clast
