Interesting - I did not realise there was a difference.  Putting the
combining mark first gives ̅S while putting it last gives S̅.  There is a
noticeable difference in these two glyphs (at least with the fonts I am
using) - putting the combing mark last sets its height to fit the S better.

With a Norwegian keyboard layout, keys like '`^"~ are all dead keys,
making it easy to type most common Western European accents or letters -
even with Windows.  On Linux there are a lot more on Alt-Gr sequences,
and then the compose key gives another level.

I will recommend he gives it a shot.  It all comes down to how much you
have to type the symbols.  I don't expect he types whole paragraphs in
IPA - and you have to type a lot before you get used to a new method.  I
believe he does most of his documents in Lyx, which has good toolbars
for IPA (by "good", I mean he finds the ordering and layout logical).
The TeX modes for Emacs could be an alternative.
