# Using the Symbol Palette in Overleaf

# Introduction

This article explores Overleaf’s **Symbol Palette**—a quick and convenient way to insert math symbols into your document. The **Symbol Palette** is a premium feature. Overleaf premium features are available to participants in Overleaf Commons, members of group subscriptions, and owners of individual subscriptions.

# Adding symbols to your document

To open the **Symbol Palette**, click the **Ω** button, which is visible when using the **Code Editor** or **Visual Editor**:

The **Symbol Palette** will open at the bottom of the editor window.

To close the **Symbol Palette** click the **Ω** button again, or use the **X** symbol located on the palette.

## Video demonstration

The **Symbol Palette** has a selection of commonly-used mathematical symbols you can browse or search by typing their name or an alias into the **Search** box. All symbols contained in the **Symbol Palette** are designed for use within mathematical content, which means they need to be inserted at a point where the LaTeX document compiler will be in so-called *math mode.* If you don’t know anything about math mode, watch the following video and read the next section.

# Math mode

Symbols shown in the **Symbol Palette** should only be inserted into your document when LaTeX is in math mode, which means they must be enclosed within special math markup:

- To put your equations in
*inline*mode enclose it within the delimiters:`\( \)`

or`$ $`

. You can also place it within the`math`

environment:`\begin{math} \end{math}`

. - To put your equations in
*display*math mode, use either`\[ \]`

or`\begin{equation} \end{equation}`

This also applies to symbols such as subscripts (_), integrals (`\int`

), Greek letters (`\alpha`

, `\beta`

, `\delta`

) and modifiers (`\vec{x}`

, `\tilde{x}`

).

If you’d like to learn more about math mode, we have a short explanation here and for a more general overview of writing math in LaTeX, check out Learn LaTeX in 30 minutes—in particular, the section Adding math to LaTeX.

If you add one of these symbols *outside* of math mode, you will see some errors when compiling your document. The error you will see depends on what else is in your document, but a common error triggered by math symbols used outside of math mode is `Missing $ inserted`

# Packages

Some symbols require you to use extra packages—if you hover on the symbol the tooltip will tell you which package you need:

For example, in this case, to use the `\iint`

symbol you need to make sure you have `\usepackage{amsmath}`

in your document preamble, i.e. before the `\begin{document}`

statement.
