The readme says "Minor mode for auto-highlighting symbol at point: symbol-overlay-mode". Does that help?

After i run (symbol-overlay-mode), but not see any visual effect, If i do somethings wrong?

If you now place point on a symbol which appears in multiple places in the current file, it should be automatically highlighted.

Oh, thank you, i guess it same as high-symbol.

Isearch symbol at point literally, without regexp-quote the symbol: symbol-overlay-isearch-literally Try symbol-overlay-isearch-literally via "s" to search the not-quoted symbol in isearch-mode.

Could you please explain more on not-quoted symbol, i could not figure out what the different with press "s" or press normal "Ctrl+S" when symbol is highlight.
