How to "Jump Back"?

This seems such an obvious (to me) need that I feel I must be missing 
something. Perhaps someone can enlighten me.

I'm editing in some source file. I use Find -> Jump to Definition 
(cmd-doubleclick) to go look at some other method in the file. ... 
OK, I've seen what I needed. Now I want to "Jump Back" to where I was 
editing and continue.

However, I can't find any means to "Jump Back". Find -> Jump to 
Selection doesn't do it, because Jump to Definition has already 
changed the selection to its target. So I have to scroll around 
manually until I relocate my starting point.

There must be a better way ... (?)
