Use a Web Link to link to external websites from within your book.
Adding a Web Link
To insert a link to an external website, select the text you’d link to make into a link and choose Web Link from the Text Feature menu.
A popover will then appear that lets you paste or type in a URL:
Once a Web Link is created, you can always click on it to bring up the popover again.
You can test your Web Link by clicking on the arrow icon () next to the URL text field, or by clicking on the link in Vellum’s Preview.
For your print edition, Vellum will automatically strip out the link aspect of your Web Links. This allows you to generate your ebook and print editions from the same Vellum file.
