Mainly, I use my arrow keys for M-x tetris. ;)

To navigate, I typically use incremental search (C-s or C-r). Because moving up line-by-line is a slow linear process which gets annoying if you're not a couple lines away from the target.

You can also use the mouse, which is a very direct way of getting where you want to go.

There's also page up/down. (If you don't want to move your hands, that's C-v and M-v.) And for moving the screen (without moving the cursor), there's a quick C-l. If you want to go to the very ends of the buffer, there's M-< and M->.

Then there's linguistic motion, because you're often thinking in terms of moving in units of text. So, M-f if forward-word; M-} is forward-paragraph.

Then there's navigating units of code. Which is like moving in units of text, but you press control too. Like C-M-f is forward-sexp, which pushes you forward a code unit. (Like a string or variable name.) C-M-a is beginning-of-defun, which gets you to the start of the function/method/whatever you're in.
