# Using Open Declaration to jump to a function in your code [edit]

This page describes how to use the Open Declaration feature to jump to another function in your code.

## Introduction

When you call a function in your code, you can quickly jump to the place where you originally declared the function. This makes it easy for you to access that function in case you are not using Code Assist or have not yet documented that function.

If you call a function that was originally declared in another file or even in another project, you can still use Open Declaration as long as you added a project reference to the project containing function.

## Instructions

To jump to a function in your code:

1. Place your cursor on the function that you are calling.
2. Press F3 to jump to the place where you declared the function. (You can also select Open Declaration from the Navigate menu.)

Your cursor automatically jumps to the place where the function was originally declared.
