Version 4.2 of package Symbol-Overlay has just been released in NonGNU ELPA. You can now find it in M-x list-packages RET.
Symbol-Overlay describes itself as: ============================================== Highlight symbols with keymap-enabled overlays ============================================== More at https://elpa.nongnu.org/nongnu/symbol-overlay.html ## Summary: Highlighting symbols with overlays while providing a keymap for various operations about highlighted symbols. It was originally inspired by the package `highlight-symbol'. The fundamental difference is that in `symbol-overlay' every symbol is highlighted by the Emacs built-in function `overlay-put' rather than the `font-lock' mechanism used in `highlight-symbol'.
