I'm now starting to write a org-mode document in place of doing it
in LaTeX, but its left me puzzled by some things, like -

a) How do you make a paragraph, or even a sentence, italic? I've
tried following the "org-mode manual" but that just shows it for
single words.

b) I am used to using "\gls{foo}" for having a glossary entry in the
text, and referring to
\newglossaryentry{foo}{name=foo,description=blah de blah}. But how
do I do it in org-mode please?

c) How do I show an item as being selected to show in the index? In
LaTeX its done using \index{foo} 

d) Are there any tutorials, or good teaching web sites please?

Thanks
Sharon.
