Q:

In vim, how do I go back to where I was before a search?

Programming in vim I often go search for something, yank it, then go back to where I was, insert it, modify it.
The problem is that after I search and find, I need to MANUALLY find my way back to where I was.
Is there an automatic way to go back to where I was when I initiated my last search?

A:

Ctrl+O takes me to the previous location. Don't know about location before the search.
Edit: Also, `. will take you to the last change you made.

A:

Use `` to jump back to the exact position you were in before you searched/jumped, or '' to jump back to the start of the line you were on before you searched/jumped.

A:

I've always done by it setting a mark.

In command-mode, press m[letter].  For example, ma sets a mark at the current line using a as the mark identifier.
To get back to the mark press ' [letter].  For example, 'a takes you back to the line mark set in step 1.  To get back to the column position of the row where you marked the line, use `a (back-tick [letter]).

To see all of the marks that currently set, type :marks.

On a slightly unrelated note, I just discovered another nifty thing about marks.
Let's say you jump to mark b by doing mb.  Vim automatically sets the mark ' (that's a single-quote) to be whichever line you were on before jumping to mark b.
That means you can do 'b to jump to that mark, then do '' (2 single-quotes) to jump back to wherever you were before.
I discovered this accidentally using the :marks command, which shows a list of all marks.
