Drawing attention to language constructs like if and return helps you visually identify patterns. When you need to know details you look into the specific code.

Drawing attention to language constructs like if and return helps you visually identify patterns. When you need to know details you look into the specific code. Highlighting the noisiest and least uniform parts of code is probably not what I really want. I don't want to draw references from an entire book in title case, with tiny section and chapter titles for example. Highlighting helps me identify code from a distance, it doesn't help me read it. It's about visual cues that eventually form into heuristics that save me time as I roam around a codebase. "Oh this is one of those" "that's not the kind of function that I'm looking for"
