Re: Prettify keywords

[pietru@caramail.com]

Have looked at prettify-symbols-mode and it is defined in prog-mode.el.
This gets me quite confused as I thought that I can only activate a single
major mode at a time on a particular buffer.

Thank you for helping me make some progress on this as I thought that the
prettify functionality would be hard to implement on tex commands whilst I
am in texinfo-mode.
