Can I link to email and PDFs?

I am working on a client project where I am using WordPress. My question is if there is any way to link highlighted text to PDFs and email by using the same method as you do with linking to web sites?

I want to be able to highlight some text and then link it to a PDF from his server opening in a new window. I want to be able to do the same with email so that it opens in the default email application.
