Search Backward Through A File

There are a number of ways to search for a match in a file. One I use quite often is hitting * while the cursor is over the word I want to find matches for. It searches forward jumping to the next occurrence of that word.

It turns out there is a way of doing the same thing, but searching backward to the previous occurrence of the word. If you hit # with the cursor over a word, it will jump backward through the file until it finds an occurrence of that word. Keep hitting # to keep searching backward.

See :h # for more details.
