There are several possibilities, depending on your forethought
and quantity of travel.
If you jump elsewhere (searching, making "large" movements such
as page-up/down, etc), you can use control+O and control+I
(that's "oh" and "eye", not "zero" and "one") to navigate the
jump-list (":help jumplist"). Control+o goes back to previous
jumps and then control+i moves forward in your list of jumps.
If you plan ahead, you can use the 26 named marks (":help mark").
You can do something like
ma
to drop the "a" mark at your current location. You can then
freely navigate all over your document, and then use
`a
or
'a
to jump back to where you were. The apostrophe just jumps to the
line, while the back-tick jumps to the line and
character-position. Since you can mark any letter you want, you
can use "ma", "mb", "mc"..."mz" to mark up to 26 locations (if
you can remember them) and them use "`a", "`b", "`c",..."`z" to
jump back to each of them. If you're forgetful, you can use the
":marks" command and vim will tell you where you can jump to with
the apostrophe/backtick. Note that some are read-only so you
can't set them, but they offer conveniences such as the
backtick-backtick: you can also use backtick-backtick to toggle
between the last two locations, jumping back and forth.
Hope this gives you several new ways to work. I use a combo of
both marks (when I remember that there's someplace important I
want to jump back to) and the jumplist to see where I've been.
