FWIW I really like using the package symbol-overlay. It highlights all occurrences of the symbol-at-point in a unique color and installs a keymap as a text property, so if point is on the symbol, some single keys run commands. E.g., with point on a symbol, n/p moves to the next/prev occurrence and r will replace all occurrences with new text (great for renaming variables). Highlighting a symbol in a unique color helps me follow logic in unfamiliar code.
