I find myself using the meta + arrow keys constantly.

When I am editing code, it would be nice if I could count underscores as words so that when I decide to rename a variable it goes to the character right after the underscore.

For example, if I have a variable named workout_disabled_color, and I press meta + , and my cursor is currently at the end of "color", then it would go to the left of the character c.

Is anybody aware of how I can do this?

Try modifying nxhtml-mode-hook.

(add-hook 'nxhtml-mode-hook
          (lambda () (modify-syntax-entry ?_ "w")))
