editing buffer -> call function

editing buffer -> call function

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.
