A necessary part of LaTeX editing is referencing equations, figures,
bibliographic entries etc. This is done with the
`\ref`

and the `\cite`

commands.
Latex-Suite provides an easy way to do this. Somewhere in the body of
the document, type in the following sentence

This is a reference to (\ref{}).

With the cursor between the `{}`

press
`<F9>`

in insert mode. Your vim session will
sprout two new windows and it should look like below:

9 \begin{document} 10 +-- 4 lines: eqnarray (eqn:euler) : \label{eqn:euler}----------------------- 14 This is the famous euler equation. I 15 will type another equation, just as 16 true: 17 +-- 4 lines: eqnarray (eqn:simple) : \label{eqn:simple}--------------------- 21 This is my contribution to mathematics. 22 This is a reference to (\ref{}<++>)<++> 23 \end{document} ~ ~ ~ test.tex [+] 22,29 Bot test.tex|11| \label{eqn:euler} test.tex|18| \label{eqn:simple} ~ ~ ~ [Error List] 1,1 All 7 \usepackage[sumlimits,]{amsmath} 8 9 \begin{document} 10 \begin{eqnarray} 11 \label{eqn:euler} 12 e^{j\pi} + 1 &=& 0 13 \end{eqnarray} 14 This is the famous euler equation. I 15 will type another equation, just as 16 true: test.tex [Preview][+] 11,2-5 46%

The cursor will relocate to the middle window which shows all
`\label`

s found in all the `.tex`

file
in the current directory.
You can scroll up and down in the middle window till you reach the
reference you want to insert. Notice how when you scroll in the
middle window, the bottom "Preview" window scrolls automatically to
show you the location of the current selection. This helps you
identify the reference with greater ease because often times,
`\labels`

are not descriptive enough or there might be too
many of them. To insert the reference, just position the cursor on
the relevant line in the middle window and press
`<enter>`

. The line which you were editing will change
to:

This is a reference to (\ref{eqn:euler})

and the bottom windows close automatically.

The `<F9>`

key also works for inserting
`\cite`

commands to reference bibliographic entries,
inserting file names for the `\inputgraphics`

command
and just plain searching for words. Click here
