I'm using emacs for perl scripting and for some unknown reason the syntax highlighting is inactivated when opening new or existing scripts.
I'm wondering if I press a key unknowingly that disactivates it.
Currently my only option is to close emacs and start a new session.
Is there a way to reactivate it?
Not sure which mode is providing the highlighting.
Thanks
