Of course we do: You can jump by searching for line contents with C-s, you can do an operation a certain number of times with M-<number> <operation>, and do an operation four times with C-u <operation>, which chains, so you can do an operation 16 times with C-u C-u <operation>.

If you want to jump to a specific line number, you can use M-g M-g <number>, or (because C-u also provides numerical arguments) C-u <number> M-g M-g.

Finally, many motion commands set the mark, so you can use C-x C-x to return to where you were and select all text between your previous and current locations.

Oh, and if you want something even better, you can use C-` to jump to the location of compiler error if you use M-x compile, you can use ag.el or helm-ag for ag integration, Ace-Jump, which is similar to EasyMotion, built-in exuberant ctags integration (and a built-in ctags clone, etags), packages for cscope integration (if you're using C), and fiinally semantic, which provides a variety of parser-based tooling if it's supported by your language.

But you can also just use C-n, etc. and we won't judge you for it.
