Just being able to jump to the top of the file, bottom of the file, beginning or end of the line, or directly to a regex pattern match or particular character already gives me some of the same satisfaction as a video game with really tight movement controls. (I also like being able to jump to lines by number, manipulate lines by number or range, and I like being able to get to the top, bottom, or middle of the screen with one or two keypresses.)

In the same vein, deleting arbitrary lines at a time, performing external operations only on lines that match a particular pattern, and saving macro recordings of repetitive manual changes all feel like multiplicative powerups. Heck, incrementing and decrementing with ^a and ^x feels like one more little cheat code. Bouncing on parentheses with % makes structured files easy to get around in.

These are all things I've done with some regularity over the years.
