In emacs abbrevs only work, I believe, on word characters, which rules
out using \ in
the key for the abbrev. I would recommend trying out yasnippet, which
is what I use
these day since it is both easy to define a "snippet" and to move the
point (cursor)
around. For instance, you would put the following text in a file in
your snippet directory
for latex mode,

#name: \frac{}{}
# --

(without a newline after $0), then after typing \f you press TAB it
expands into \frac{}{}
placing the cursor between the first two braces. Press TAB again and
the cursor moves
between the second pair of braces. Press TAB a third time and the
cursor is placed after
the last brace. There does appear to be a bug where \f does not expand
if the \ is the first
character on the line, but otherwise it works for me. You can find yasnippet at
