Hi everyone,
I wonder how to call a function everytime a buffer is updated. For example :
- I want to highlight each instance a specific word
- Every time I write this word after the search, I want to highlight it
automatically or if I delete an instance of it clear the overlay.
Can you help me ?
Thx
Sebastien

Use the hook `after-change-functions'.
Or you can leave the work to `highlight-regexp'. Look at
highlight-symbol.el[1] for an example.
