Assume that we are writing a mathematical paper and we want to use the
popular amsmath package. We will use some functionality which
Latex-Suite provides specifically for including LaTeX packages,
providing options etc. Navigate to before the
\begin{document} line (The portion of the document
before the \begin{document} is called the
preamble in LaTeX). On an empty line in the
preamble, type the single word amsmath and then press
<F5> in normal mode. The line will change to
\usepackage[]{amsmath}<++>
with the cursor positioned conveniently between the
[]'s. For now, do not worry about the trailing
<++> at the end of this line. Assume we want to
provide the sumlimits options to amsmath. You can
either type in this option manually, or choose from a menu of package
options which Latex-Suite automatically creates when you insert a
package using <F5>. With the cursor still
placed between the [], goto TeX-Suite >
Packages > amsmath Options. Choose the
sumlimits option. The package line should get
converted to:
\usepackage[sumlimits,]{amsmath}<++>
with the cursor before ]. Press
<C-j> in insert mode. You will see the cursor
jump to the end of the package line and the trailing
<++> will disappear. What just happened?! You had
your first taste of Placeholders. Read more about
them (later) here.
In short, pressing <C-j> in insert mode takes
you to the next <++> in the text.
