Quick jump between InDesign pages

Lets say you have a multi-page document and you’re jumping between two pages to see how text flows, etc. There’s an easier way than using the Command + J and number command. You can use the Command + Page Up/Page Down keys. For example, if you’re on page 2 and jump to page 8 normally, you can hit Command + Page Up to quickly go back to page 2 and then hit Commaned + Page Down to go back to page 8 again.
