the description at ":help gd" seems to indicate that "gd" is intended to
be used on C-like code, i.e., languages that use curly braces to define
blocks. In a lot of places Vim assumes that a C function starts with an
opening curly brace in the first column. Vim does not actually have a
concept of programming language structures. With "gd" the search for
"myacro" will start at the curly brace that Vim *thinks* is the start of
a function. As long as your text "{Big long section name ..." is on a
line of its own, the search for "myacro" will start there and stop at
the place where your cursor is already located.

Maybe with LaTeX code "gD" might be a better alternative, although this
will always stop at the first occurrence of a word and ignore later
re-definitions.

Jürgen
