# Navigating XML schemas

When you are working in the Source view, you can use F3 to navigate through the file. You can place your cursor in any of the following items and press the F3 key to jump to the item it refers to. You must place your cursor exactly in the location of the reference (for example between the double quotes for `type = " "` or `base = " "`):

- Element or attribute declaration's type
- Restriction (you jump to the base type it refers to)
- List (you jump to the type it refers to)
- Union (you jump to the type it refers to)
- Element references
- Key references
- Group references
- Attribute references
- Attribute group references
- Import, include, and redefine element (the external schema will open in the XML schema editor. This only works with schemas in the workspace).

For example, if you place your cursor anywhere in the bolded text below and click F3:

`<element name="shipTo" type="po:USAddress"></element>`

the cursor will automatically jump to the location in the file where the type USAddress is defined.

Or, if you place your cursor anywhere in the bolded text below and click F3:

`<element ref="po:ContactElement"></element>`

the cursor will automatically jump to the location in the file where the global element ContactElement is defined.

This works across files. For example, if the type you have selected is defined in another XML schema and you click F3, you will automatically be taken to that file.
